Oblivions good, I wasn't a fan of War Of The Worlds.
I don't have any one favorite, I prefer the older movies. If I had to list just Sci-fi films it would go something like, "Aliens", "The Matrix", "Dark City", "Terminator 2", "A Space Odyssey", "Predator", "Gattica" (was really good). "Moon" was good. I really like Eternal Sunshine of the Spotless Mind though not really Sci-fi.
