5 Worst Soft Sci-Fi Movies of All Time, Ranked

Image via Warner Bros. Pictures Published Sep 27, 2026, 5:42 PM EDT Sign in to your Collider account Bad soft sci-fi can be weirdly fascinating because there is nowhere for it to hide (hard sci-fi have all that technical wizardry to hide behind). But nobody is checking the orbital math or asking whether the alien biology would survive peer review in a soft sci-fi. The movie gets more freedom which means character, imagination, world-building, and basic storytelling have to do the heavy lifting. When those fail too, things get ugly fast. And these movies, therefore, all fail in completely different ways by extension. Let’s dig in. 5 'Jupiter Ascending' (2015) Image Via Warner Bros. Jupiter Jones (Mila Kunis) cleans houses in Chicago and believes her life is going nowhere until she discovers that, on a genetic level, she is effectively the reincarnation of a dead intergalactic matriarch. That makes her the legal heir to Earth, which turns one miserable morning into a fight involving royal space dynasties, human harvesting, flying boots, and Caine Wise (Channing Tatum), a genetically engineered former soldier who is part wolf. There are ideas everywhere in Jupiter Ascending. That is almost the problem. The Abrasax family treats whole planets like agricultural property because human beings can be processed into a life-extending serum. Bureaucracy exists on a cosmic scale, which leads to the genuinely funny sequence where Jupiter spends ages moving through government offices just to establish ownership. Then the story buries her under another kidnapping, another rescue, another speech about inheritance. Even Eddie Redmayne’s Balem Abrasax speaks like every sentence is either a whisper or a volcanic eruption. This should have been gloriously strange. It mostly feels like someone brought five movies to the same meeting and nobody was allowed to say no. 4 'The Host' (2013) Image via Open Road Films Aliens called Souls have taken over most human bodies, leaving only a small resistance population hiding from them. Melanie Stryder (Saoirse Ronan) is captured and implanted with a Soul named Wanderer, but Melanie’s consciousness refuses to disappear. The Host therefore has two people sharing one body, arguing internally while Wanderer is supposed to help locate the humans Melanie loves. That is actually a strong soft-sci-fi setup because identity, memory, love, and bodily control are all sitting right there. The movie somehow makes it feel flat. Melanie regularly speaks inside Wanderer’s head, so entire emotional conflicts become voice-over arguments where one person is literally talking to herself. The resistance community should create serious tension because some members see Wanderer as an enemy wearing Melanie’s body. Instead, the romantic triangle starts swallowing attention, including the very awkward fact that Melanie and Wanderer can develop feelings for different men while occupying the same physical person. There is interesting material buried in here. You just have to dig through a lot of staring to reach it. 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 3 'After Earth' (2013) Image via Columbia Pictures After Earth is basically a survival story about a son desperate to prove himself to a father he can barely connect with. A thousand years after humanity abandons Earth, military commander Cypher Raige (Will Smith) crashes there with his teenage son Kitai (Jaden Smith). Cypher is badly injured, their emergency beacon is destroyed, and Kitai has to travel across a planet full of dangerous evolved wildlife to reach the ship’s tail section and call for help. The movie’s big concept is “ghosting,” the ability to eliminate fear so completely that the alien Ursa cannot detect you. The problem is that characters discuss fear in stiff slogans until an emotion every human understands starts sounding like corporate training material. Kitai encounters aggressive animals, leaps from cliffs, nearly freezes at night, and eventually has to confront an Ursa, yet the adventure rarely has the pulse it should. Even the bizarre claim that Earth’s animals have evolved specifically to kill humans, despite humans being gone for centuries, gives you more to argue about than the actual relationship at the center. A father coaching his terrified son through a hostile planet should hit hard. Here, it mostly feels strangely distant. 2 'The Adventures of Pluto Nash' (2002) Image via Warner Bros. It is 2087, people live on the Moon, and Pluto Nash (Eddie Murphy) owns a nightclub in a lunar colony. Gangsters want to buy the club, Pluto refuses, and shortly afterward the place gets blown up. From there, The Adventures of Pluto Nash sends him through a future full of robot bodyguards, casinos, organized crime, cloning, and enough lunar businesses to suggest humanity reached space mainly so it could rebuild Las Vegas. The weirdest thing is how little excitement comes from any of it. Pluto has a robotic assistant named Bruno (Randy Quaid) who gets more mileage out of physical comedy than most of the expensive futuristic setting. The villain mystery eventually leads to Rex Crater, a criminal boss whose identity adds another layer of cloning nonsense to a plot already struggling to stay interesting. There are moon cars, shootouts, holograms, and artificial gravity jokes, yet whole stretches feel like everybody is waiting for the movie to become fun. It reportedly cost around $100 million to make, and almost none of that money appears to have purchased a reason to care. 1 'Battlefield Earth' (2000) Image via Warner Bros. Pictures By the year 3000, Earth has been conquered by the Psychlos, humanity has been reduced to scattered primitive groups, and Terl (John Travolta) oversees mining operations from a giant alien facility. He captures Jonnie Goodboy Tyler (Barry Pepper) and decides to use him for an illegal gold-mining scheme after discovering a deposit Terl wants for himself. Battlefield Earth then makes the incredible choice to have Terl educate Jonnie using a rapid-learning machine, effectively teaching the human prisoner everything he needs to eventually fight back. It gets much worse. Jonnie and other humans find old military equipment and somehow get enough use out of it to challenge an advanced alien civilization that conquered Earth in minutes. The Psychlos are defeated through a plan involving their home planet’s atmosphere, nuclear weapons, and information humans learn with almost comical speed. Meanwhile, half the movie is shot at tilted angles, as though the camera itself is trying to escape. Terl laughs, snarls, schemes, and repeatedly underestimates people he personally made smarter. It is not boring, which deserves some credit. But as soft sci-fi world-building, storytelling, or basic common sense, Battlefield Earth is the kind of disaster you almost have to watch once just to understand how real it is.
