Ars Technica has come up with as close to a definitive list of essential science-fiction movies as any of us are likely to come across any time soon. I quarrel with only one inclusion: Frankenstein (1931). It’s a horror movie more than it is a sci-fi one. And I quarrel with only one–glaring–omission: the list should include (and you should see) Interstellar (2014). For the life of me, I can’t imagine why they left it out.
Many of these films are based on novels or short works, and the editors have been kind enough to tell us which ones are so based. The included sub-list of really bad sci-fi films is fun to read (and the films on that list truly are bad), but part of me wishes they had dropped that idea and gone a little farther with the main list, adding films like Interstellar, like Solaris (2002), and like Colossus: The Forbin Project (1970) that deserve to be there.
