Well, I've seen: 1. Falling Down (mediocre), 3. The Adventures of Buckaroo Bonzai (very enjoyable wild romp), 4. The Hidden (neat skiffy flick about an alien which can pass from human to human, but not nearly as good as the Denzel Washington/John Goodman Fallen which is the same story but with a fantasy rather than a SF rationale), 10. Breakdown (quite decent), 15. Brannigan (sub par, even for Wayne), 19. Time After Time (I'm a sucker for time-travel stories who thought this was a piece of crap), and 20. Idiocracy (so bad I couldn't finish it). That's 7 out of 25.

Of course, I'd have had a whole different list of movies...

Best is very debatable here
