10 science fiction films for the 'thinking man'

Jeff Giles of Rotten Tomatoes has put together a list of what he believes to be the top ten sci-fi films for the thinking man:

10. Planet of the Apes
9. Dark City
8. Sleeper
7. Gattaca
6. Primer
5. Children of Men
4. Solaris (1972)
3. Close Encounters of the Third Kind
2. Blade Runner
1. 2001: A Space Odyssey

I think #1 and #2 are spot on, but Solaris deserves third spot. Gattaca and Children of Men are both great films, but a bit overrated -- particularly the latter. Close Encounters at #3!? And where the hell is The Matrix and Ghost in the Shell?

Oy, I need to straighten this out; Giles's list has some problems. Here's my (i.e. the definitive) list of the best "thinking man's" science fiction:

10. The Day the Earth Stood Still (1951)
9. Planet of the Apes
8. Contact
7. AI
6. Ghost in the Shell
5. Metropolis
4. The Matrix
3. Solaris (1972)
2. Blade Runner
1. 2001: A Space Odyssey
