Inland Empire: Over three hours of strangely hypnotic David Lynch.
District 9: South African SF fable about prejudice and violence, as a spaceship full of aliens arrives in Johannesberg and the inhabitants are forced into shanty-towns, excluded from society and dehumanised in horrible, but entirely predictable ways. Told as a mock-doc about an incident where a middle manager with a defense contractor, charged with clearing an alien shanty-town, is infected with a mystery substance, the CGI is the best I've ever seen in a SF film.
Superman II: Better than the rest of them, mainly by virtue of having some good lines and some of those Eighties visuals that are heavily Expressionist-inspired. But really, both Superman and Lois Lane are so amazingly thick you wonder how they remember to keep breathing.
