HBO's Harry Potter Has A Huge Fantasy Challenge To Overcome

Published Aug 20, 2026, 11:30 PM EDT Angel Shaw is a Lead Writer and Critic on ScreenRant's TV team, covering new-release and classic TV shows across all major streaming platforms. She has been a writer with ScreenRant since 2022 and specializes in Harry Potter, The Lord of the Rings, and fantasy. Angel holds a bachelor's degree in language interpreting and is passionate about all things culture and communication—especially in how it relates to popular media throughout history (from Shakespeare to Friends to Game of Thrones). The Harry Potter franchise has stood as a solid pillar on the fantasy landscape for nearly 30 years, but that doesn't necessarily guarantee HBO's success. While the announcement of a new TV show adaptation of J.K. Rowling's book series came as a bit of a surprise, it makes some sense that HBO would make this move. Fantasy is more of a heavy hitter today than it even was a decade ago. Game of Thrones was a massive global phenomenon that essentially helped the genre burn brighter. When Game of Thrones came to a close, HBO wasted no time kicking off spinoffs like House of the Dragon and A Knight of the Seven Kingdoms. Author George R.R. Martin may not have finished A Song of Ice and Fire yet, but there's no doubt that he is among the most influential fantasy creators of our age. While J.R.R. Tolkien's The Lord of the Rings never stopped being popular, the resurgence in projects from New Line Cinema, Warner Bros, and Amazon Prime Video can almost certainly be attributed to the renewed interest Martin brought to the fantasy genre. Given how much more popular fantasy is in the mainstream today, a Harry Potter revival should be a booming success. However, while HBO's new TV show is unlikely to flop entirely, we shouldn't expect the same phenomenon we saw back when Rowling was still actively publishing books and Warner Bros. was still working on adaptations. In that age, contemporary adolescent fantasy was all the rage, but things have changed. High Fantasy Is Dominating The Entertainment Industry (& That's Bad For Harry Potter) Back in the 2000s especially, contemporary fantasy was the newest, hottest thing. Decades past had been dominated by stories that fit the tone of Tolkien's The Lord of the Rings, Dungeons & Dragons, and A Song of Ice and Fire. There was a dedicated fanbase here, but these sorts of lore-heavy and ancient-world fantasy stories still belonged to a more niche audience. Peter Jackson's Lord of the Rings trilogy was a massive success, and Martin's books had gained traction, but Harry Potter was far more hip. The arrival of Game of Thrones changed that. Martin's books were popular in the 2000s, but not nearly as mainstream as Harry Potter. The TV show was another story entirely. For years, the fantasy landscape, especially book-to-screen adaptations, targeted children, teens, and young adults. Game of Thrones was a world of pure high fantasy, but packaged and delivered straight to mature audiences instead. Suddenly, high fantasy wasn't just popular among Tolkien and Dungeons & Dragons nerds. It seemed the whole world had fallen in love. While Game of Thrones has since come to a close, high fantasy is more popular than ever. The franchise has expanded, other shows like The Witcher and The Wheel of Time have found their way to the screen, and everyone is holding their breath for Brandon Sanderson's works to finally get their Apple TV adaptations. Once again, it's all about medieval-like worlds, dragons, horses, knights, warring kingdoms, and ancient artifacts. Harry Potter, targeted at young audiences, doesn't carry the same weight. The Harry Potter Books & Movies Might Not Have Been So Popular If They Came Out Today Of course, because Harry Potter maintains such a strong fanbase, HBO is sure to do well enough with the upcoming TV show. Most likely, it won't be canceled or considered a loss. However, it shouldn't be assumed that we will see the return of the sort of hype we saw in the 1990s and 2000s. Back in the day, lines for Harry Potter books, movies, and merchandise stretched out into the streets of the biggest cities across the globe. For a whole variety of reasons, that isn't likely to happen again today. Harry Potter, though targeted at children, is meant to appeal to a wide audience base. This is all part of why it was such a solid success (And why it remains culturally significant 30 years later). As previously mentioned, however, the modern entertainment industry prioritizes adult-aimed fantasy projects. Game of Thrones and its spinoffs, The Witcher, and beyond have a more limited audience (people over 18), but it's what sells. If Rowling published her first Harry Potter book today, it wouldn't fit within that scope by any means. Not only is it not a high fantasy series, but it isn't nearly as dark or gritty as today's greatest hits—at least not at first. As Harry's story gets more mature, that begins to change, but the series would have to survive the modern fantasy landscape long enough to reach that point, and it's hard to say anymore that that would happen. HBO's Harry Potter Has Already Made The Best Choice It Can To Overcome This Challenge Credit: HBO via MovieStillsDB If Harry Potter were a brand new TV show bringing Rowling's works to the screen for the very first time in 2026, it might have gone completely under the radar. Luckily for HBO, this is a well-established franchise, absolutely packed with pop-culture nostalgia. Viewers of all ages have fond memories of consuming this story in decades past, so there are sure to be more than enough willing to tune in. It also helps that, while Harry Potter is still considered a contemporary fantasy, it won't exactly be modern. Harry Potter canonically started school at Hogwarts in 1991, and HBO is officially recognizing that with its series. The upcoming TV show shows clear signs of its '90s setting, and that's really quite clever on the part of the creators. There's another layer of nostalgia involved, thus drawing in those older audiences while avoiding the overly polished, overly contemporary form of fantasy that is no longer as popular. Pair this with the already outdated aesthetic of the magical world in Harry Potter, and HBO's TV show has gained a fair edge. The layered-up nostalgia factor will certainly help Harry Potter's success, and the fact that HBO has raised the maturity rating of season 1 to TV-14 (rather than the first movie's PG rating) further indicates that the company is fully aware of this obstacle. With the high fantasy worlds of Tolkien and Martin back on top, Rowling's Harry Potter isn't likely to get its own resurgence for several more years to come. Still, those careful creative choices will help ensure the show stays alive long enough to make it that far.
