If there is a storyline present, it is typically underdone and rife with plot holes while lacking any semblance of thematic ideal or messaging, the writing of the dialogue is just one cringe-worthy, ill-fated line after another, and the less said about the acting, the better. Usually, this brand of sci-fi schlock can be spotted a mile away, but sometimes the marketing team have more of an idea of what the movie should be and successfully entice the masses into spending their hard-earned coin in the hope of seeing something special. From modern misfires that promised blockbuster brilliance to infamous flicks from decades ago that have either been forgotten or endured as hits of so-bad-it's-good cinema, these movies did manage to lull some unfortunate souls with their impressive promotional material only to throw their hopes and expectations right back in their faces. You can't judge a book by its cover, nor can you judge a movie by its trailer, a sad fact that these sci-fi disasterpieces serve as a testament to. 10 'Moonfall' (2022) Image via Lionsgate There is no denying that Moonfall has an enticing premise, one that its trailers were smart to capitalize on, not only with the promise of high-octane disaster spectacle, but with the allure of some savvy CGI as well. The end result wasn't quite so impressive. Its story—revolving around a team of NASA experts and a geeky scientist tasked with preventing our off-its-orbit moon from crashing into Earth—runs less as a relentlessly thrilling descent into absurd chaos and more as a misguided and mundane melodrama that is occasionally interrupted by some exciting set pieces. It is a brainless blockbuster with an identity crisis, one stranded between the emotionally-charged carnage of movies like Armageddon and the intellectual science-fiction detail of flicks like Gravity and The Martian. This no-man's-land it finds itself in simply offers nothing of substance or great spectacle, making it a tiresome 130-minute misfire that is irritating more so than anything else. Failing even as a so-bad-it's-good guilty pleasure, Moonfall is a catastrophic calamity that, despite the intrigue of its trailers, has come to be one of the worst movies of the 2020s so far and as well as a pathetic box office flop. 9 'Battlefield Earth' (2000) Image via Warner Bros. Pictures It may seem absurd to consider today, given the film's infamous standing in cinematic history, but Battlefield Earth was a production that, on paper, had some merit. After all, who doesn't love the notion of a young underdog hero called Jonnie Goodboy Tyler (Barry Pepper) rising up to defy the tyranny being imposed on humanity by an evil race of giant humanoid aliens in the distant future. Unfortunately, in practice, the adaptation of L. Ron Hubbard's epic sci-fi novel "Battlefield Earth: A Saga of the Year 3000" never reaches the standard it should as a monumental genre epic, or even as an enjoyable dose of blockbuster bombast. At the very least, it should have been entertaining, and even if audiences didn't believe the trailer's promise of a movie that would usher in the sci-fi splendor of the 21st century, they still probably expected something action-packed and invigorating. Needless to say, this wasn't the case. Furthermore, the production suffered a plethora of controversies and mishaps, including a significant legal issue revolving around fruadulant claims to secure funding. Battlefield Earth has come to be known as one of the most unwatchably horrendous and insultingly ludicrous movies ever made. 8 'A.I. Artificial Intelligence' (2001) Image via Warner Bros. Pictures A.I. Artificial Intelligence may not be one of the absolute worst sci-fi movies ever made, but it is certainly fair to say it fell short of expectations. To be fair, expectations are always astronomically high when a sci-fi blockbuster directed by Steven Spielberg comes around, but his 2001 drama presented a pivot away from his propulsive energy, one that audiences weren't completely on board with. Based on Brian Aldiss's short story "Supertoys Last All Summer Long," the somber movie follows a child A.I. who is designed to be loved. When he is abandoned, he sets out with the hope of becoming a real boy so that he may win the affection of his mother. It was clunky on arrival, and it certainly hasn't aged well into the modern world of technological suspicion and A.I. paranoia, even if Haley Joel Osmet's lead performance is emotionally evocative and Spielberg's direction is, as always, impressive. While memorable for some of its more heartbreaking beats, A.I. Artificial Intelligence is, above all else, a movie of wafting monotony, a slow and cumbersome affair that never kicks into gear and, through its awkward thematic center, becomes a largely uninspiring misfire. 7 'The Day the Earth Stood Still' (2008) Image via 20th Century Fox Hollywood remakes of classic movies are rarely welcomed by the masses, but occasionally there comes an exception to the rule that compels by capitalizing on the original's spectacle and thematic gravitas in a modern-day setting. The Day the Earth Stood Still could easily have been an example of this, with the 1951 original's core themes of political distrust, mankind's appetite for war and destruction, and the hostility that comes with suspicion and danger being perhaps even more relevant in the 21st century than they were in the early Cold War era. Sadly, the 2008 rendition of the movie doesn't want to grapple with any of that. Instead of marking a scorching indictment of how little society and global politics had changed over almost 60 years, it simply wants to be a special effects-led disaster blockbuster flaunting spectacle and style, but little substance. What made this worse is the initial trailer did promise this brand of thematic grit and commentary. 6 'Escape from L.A.' (1996) Image via Paramount Pictures Even as a dated, low-budget, B-movie flick that is now 45 years old, 1981's Escape from New York maintains a sense of charm and inviting absurdity with its ridiculous, high-concept dystopian premise and Kurt Russell's typically magnetic lead performance. Unsurprisingly, when it was announced that John Carpenter and Kurt Russell were returning to work on a sequel 15 years later, fans of the original cult gem were overjoyed. Sadly, they were not rewarded, with Escape from L.A. failing even to be a so-good-it's-bad treat of B-movie bombast, and instead dwindling as an unfulfilling and often embarrassing follow-up that left those who paid to see it in theaters both wincing in agony and wondering if they could get a refund. Russell, who was even able to make The Christmas Chronicles movies somewhat entertaining with his enthusiasm and zest, has never looked less interested in a film, and still his performance is a highlight amid a brain-numbing barrage of illogical plotting, clunky action sequences, and some of the worst CGI cinema has ever seen. Collider Exclusive · Sci-Fi Survival Quiz Which Sci-Fi World Would You Survive? The Matrix · Mad Max · Blade Runner · Dune · Star Wars Five universes. Five completely different ways the future went wrong — or sideways, or up in flames. Only one of them is the world your instincts were built for. Eight questions will figure out which dystopia, galaxy, or desert wasteland you'd actually make it out of alive. 💊The Matrix 🔥Mad Max 🌧️Blade Runner 🏜️Dune 🚀Star Wars TEST YOUR SURVIVAL → 01 You sense something is deeply wrong with the world around you. What do you do? The first instinct is often the truest one. APull on every thread until I understand the system — then figure out how to break it. BStop asking questions and start stockpiling — food, fuel, weapons. Questions don't keep you alive. CKeep my head down, observe carefully, and trust no one until I know who's pulling the strings. DStudy the patterns. Every system has a rhythm — learn it, and you learn how to survive it. EFind the people fighting back and join them. You can't fix a broken galaxy alone. NEXT QUESTION → 02 In a world of scarcity, what resource do you guard most fiercely? What we protect reveals what we believe survival actually requires. AKnowledge. If you understand the system, you don't need resources — you can generate them. BFuel. Everything else — movement, power, escape — runs on it. CTrust. In a world of fakes and informants, a truly reliable ally is rarer than any commodity. DWater. And after water, information — the two things empires are truly built on. EShips and credits. The galaxy is big — you survive it by being able to move through it freely. NEXT QUESTION → 03 What kind of threat keeps you up at night? Fear is useful data — if you're honest about what you're actually afraid of. AThat reality itself is a lie — that everything I experience has been constructed to keep me compliant. BA raid. No warning, no mercy — just the roar of engines and then nothing left. CBeing identified. Once someone with power decides you're a problem, you're already out of time. DBeing outmanoeuvred — losing a political game I didn't even know I was playing. EThe Empire tightening its grip until there's nowhere left to run. NEXT QUESTION → 04 How do you deal with authority you don't trust? Every dystopia has a power structure. Your approach to it determines everything. ASubvert it from the inside — learn its rules well enough to weaponise them against it. BIgnore it and stay out of its reach. The further from any power structure, the better. CAppear to comply while doing exactly what I need to do. Visibility is the enemy. DManoeuvre within it carefully. You can't beat a system you refuse to understand. EResist openly when I have to. Some things are worth the risk of being seen. NEXT QUESTION → 05 Which environment could you actually endure long-term? Survival isn't just tactical — it's physical, psychological, and very much about where you are. AUnderground bunkers and server rooms — cramped, artificial, but with access to everything that matters. BOpen wasteland — brutal sun, no shelter, constant movement. At least the threat is honest. CA dense, rain-soaked city where you can disappear into the crowd and nobody asks questions. DMerciless desert — extreme heat, no water, and something enormous living beneath the sand. EThe fringe — backwater planets and busy spaceports where the Empire's attention rarely reaches. NEXT QUESTION → 06 Who do you want in your corner when things fall apart? The company you keep is the clearest signal of who you actually are. AA tight crew of believers who've seen behind the curtain and have nothing left to lose. BOne or two people I'd trust with my life. Any more than that and someone talks. CNobody, ideally. Alliances are liabilities. I work alone unless I have no choice. DA community bound by shared hardship and mutual survival — people who need each other to last. EA ragtag team with wildly different skills and total commitment when it counts. NEXT QUESTION → 07 Where do you draw the line — if you draw one at all? Every survivor eventually faces a moment that tests what they're actually made of. AI won't harm the innocent — even the ones who'd report me without hesitation. BI do what I have to to protect the people I've chosen. Everything else is negotiable. CThe line shifts depending on who's asking and what's at stake. DI draw a long-term line — nothing that compromises my people's future, even if it'd help now. ESome lines, once crossed, can't be uncrossed. I know which ones they are. NEXT QUESTION → 08 What would actually make survival worth it? Staying alive is one thing. Having a reason to is another. AWaking others up — dismantling the illusion so no one else has to live inside it. BFinding somewhere — or someone — worth protecting. A reason to keep moving. CAnswers. Understanding what I am, what any of this means, before time runs out. DLegacy — shaping the future in a way that outlasts me by generations. EFreedom — for myself, for others, for every world still living under someone else's boot. REVEAL MY WORLD → Your Fate Has Been Calculated You'd Survive In…Your answers point to the world your instincts were built for. This is the universe your temperament, your survival instincts, and your particular brand of stubbornness were made for. The MatrixYou took the red pill a long time ago — probably before anyone offered it to you. You're a systems thinker who can't help but notice the seams in things. You're drawn to understanding how the system works before figuring out how to break it. You'd find the Resistance, or it would find you — your instinct for spotting constructed realities is the machines' worst nightmare. You function best when you have access to information and the freedom to act on it. The Matrix built an airtight prison. You'd be the one probing the walls for the door. Mad MaxThe wasteland doesn't reward the clever or the well-connected — it rewards those who are hard to kill and harder to break. That's you. You don't need comfort, community, or a cause larger than the next horizon. You need a vehicle, a clear threat, and enough fuel to outrun it — and you're good at all three. You are unsentimental enough to survive that world, and decent enough — just barely — to be something more than another raider. In the wasteland, that distinction is everything. Blade RunnerYou'd survive here because you know how to exist in moral grey areas without losing yourself completely. You read people accurately, keep your circle small, and ask the questions others prefer not to answer. In a city where humanity is a legal designation rather than a feeling, you hold onto something that keeps you functional. You're not a hero. But you're not lost, either. In Blade Runner's world, that distinction is everything. DuneArrakis is the most hostile environment in the known universe — and you are precisely the kind of person it rewards. Patience, discipline, and political awareness are your core strengths — and on Arrakis, they're survival tools. You understand that the long game matters more than any single victory. Others come to Dune and are consumed by it. You'd learn its logic and earn its respect. In time, you wouldn't just survive Arrakis — you'd begin to reshape it. Star WarsThe galaxy far, far away is vast, loud, and in a constant state of violent political upheaval — and you wouldn't have it any other way. You find meaning in being part of something larger than yourself — a cause, a crew, a rebellion. You'd gravitate toward the Rebellion, or the fringes, or whatever pocket of the galaxy still believes the Empire's grip can be broken. You fight — not because you have to, but because standing aside isn't something you're capable of. In Star Wars, that willingness is what makes all the difference. ↻ RETAKE THE QUIZ 5 'Independence Day: Resurgence' (2016) Image via 20th Century Studios When it was released in 1996, Independence Day took over the world as a must-see blockbuster blitz, a heart-racing sci-fi action epic that fast became an instant classic of the genre and was instrumental in reviving sci-fi cinema as a mainstream box office drawcard after a brief lull. 20 years later, many stars and even director Roland Emmerich returned to deliver another dose of ass-kicking excitement as the alien invaders from the first film return to Earth with renewed resources, a greater army, and an even more vindictive desire to eradicate humanity. Seeing the CGI spectacle and the litany of new and returning stars in the trailer made Independence Day: Resurgence one of the buzz blockbusters leading into the summer of 2016, but when it finally released, it became abundantly clear that the original needed no successor. While some of its visual effects are impressive, it lacks the propulsive narrative drive and enthusiastic heart that made the first movie such an invigorating sensation. It remains one of the worst movies audiences have been forced to endure this century, and it is no surprise that many who were tricked into seeing it have since forgotten it ever existed. 4 'Body Snatchers' (1993) Image via Warner Bros. While there has been some growing appreciation for 1993's Body Snatchers in more recent years, it is difficult to overlook its standing as one of the more miserable misfires of the 1990s. Both the 1956 and 1978 versions of Invasion of the Body Snatchers had come to be, and still are revered as, defining classics of sci-fi/horror cinema, so it is understandable that many were hoping a '90s spin on the story could mark another genre hit, or at least an exciting 90 minutes at the movies. Instead, it dumbs down the suspense of the story, trading atmospheric tension for bone-headed action absurdity as it shifts the eerie alien invasion tale from a suburban parable of societal threats and paranoia to a bumbling, all-guns-blazing shootout on a military base. In doing this, it completely misconstrues the intent of Jack Finney's original novel, and almost purposefully eschews its thematic commentary on social anxiety and hysteria for underwhelming action bombast. To say it doesn't work would be an understatement, with Body Snatchers succumbing to a horrific box office intake and promptly being forgotten. 3 'Rollerball' (2002) Image via Metro-Goldwyn-Mayer Pictures Another ill-fated remake that failed to recapture the essence of the original, Rollerball lacks the social criticism of its forebear while its emphasis on the action violence of the titular sport is realized so haphazardly that it becomes an egregious, cluttered eyesore rather than a propulsive dose of physical carnage. Despite its standing today as one of the most forgettable mishits of all time, it is easy to see why some genre enthusiasts in 2002 were eager to see what it could offer given its eclectic cast, including Jean Reno, most notably, the direction of John McTiernan, the man behind such blockbuster classics as Die Hard and Predator. Unfortunately, the movie not only capitulated as a critical disaster and a commercial disgrace that tarnished the legacy of the original film's cult status, but it also led to a shocking end to McTiernan's career, with the director eventually being sentenced to a year in federal prison following an investigation into his hiring of a private investigator to illegally wiretap the producer's phones. What could have been a timely re-imagining of a commentary on corporate amorality, authority, and the expendability of individuals, or even just a rollicking hit of action intensity, instead became a calamitous, career-ruining disaster that is only remembered for being one of the worst movies ever made. 2 'DeepStar Six' (1989) Image via Tri-Star Pictures Most people today would be completely unaware that DeepStar Six even exists, and there are a couple of reasons for this, including that in many parts of the world it screened in theaters just months before the looming release of James Cameron's underwater sci-fi thriller The Abyss which had its own wave of hype and a very similar premise. The far more significant reason, however, is that the film is an atrocious misunderstanding of how suspense is cultivated and manipulated, with its story having no regard at all for grounding characters or establishing core bonds. Despite the fact that the film lacks tension and runs with an uninspired plot, DeepStar Six did entice some viewers with its attention-grabbing trailer. It promised a nerve-rattling pressure-cooker playing on the claustrophobic sensory nightmare of being trapped underwater with a giant monster that is hellbent on hunting you down. Sadly, it never delivered on this expectation, and it has been completely forgotten over the years. 1 'Robocop 3' (1993) Image via Metro-Goldwyn-Mayer Studios By the time RoboCop 3 came out in theaters, audiences should have known that the franchise was on its last legs. The thematic undercurrent of the first film had all but vanished and the impactful intensity of the action was nowhere to be seen. But still, many held out hope that the third installment could be something of a return to form. To cut a long story short, it wasn't. With a recalibrated tone that eschewed the violent punch of the earlier films with a more kid-friendly fluffiness, RoboCop 3 was the final nail in the coffin of the franchise, in many ways, an underwhelming farewell that confirmed to everyone that the action hero that loved in 1987's RoboCop was done for. What few action sequences the movie did provide were borderline insulting to the fanbase, while the storytelling oscillates between uninspired callbacks and asinine attempts to appeal to a wider audience. A box office failure, a franchise-killing misfire, and an entirely forgettable example of cash-grab carnage in Hollywood, RoboCop 3 is now remembered as one of the worst movies to have ever been released as a blockbuster hopeful, that is if it is remembered at all. RoboCop 3 Release Date November 5, 1993 Runtime 104 minutes Cast Robert John Burke RoboCop
