I've seen them all, including the short films. Here's my list from Best on down. Just my opinion:
1. The Shining (Best horror film ever made)
2. Dr. Strangelove (best satire ever)
3. Barry Lyndon (best cinematography ever)
4. A Clockwork Orange (best dystopian film ever)
5. Paths of Glory (best anti-war film ever)
6. 2001 (Incredible innovation and ahead of its time)
7. The Killing (Great heist film)
8. Eyes Wide Shut (Great use of music throughout)
9. Full Metal Jacket (loved the first half, 2nd half loses a bit)
10. Lolita (actually a very funny film considering the subject matter)
11. Spartacus (more of a Kirk Douglas film, Kubrick was brought on after the first director was fired)
12. Killer's Kiss (You can see the potential early on)
13. Fear and Desire (a dud)
