After an absolutely crushing run at the box office earlier this year, the best sci-fi movie of 2026 is continuing its dominance by completely taking over its new streaming home. 2026 has been a strange year for the sci-fi genre. Steven Spielberg’s (one of the kings of the genre) Disclosure Day drastically underperformed, as did Star Wars: The Mandalorian and Grogu. Meanwhile, Backrooms (which blends horror with sci-fi) was a major success. But, at least until Denis Villeneuve’s Dune: Part Three drops later this year, there is one 2026 sci-fi movie that is undoubtedly the best so far, and it’s now on streaming.
