I've been in a sci-fi movie mood lately. I compiled a list of movies from various "top sci-fi movies" lists. If a sci-fi movie isn't on this list, it's most likely because I've already seen it (or it's a terrible movie). Anyway, this list is so long, I'm not really sure what I should watch next. What do you recommend? I'm also open to suggestions that aren't on the list.
