Hollywood has become a piece of shit :S There are only a handful of actually good movies released in recent years. I watched Cloud Atlas for like 5 times now, that thing is deep as, though - requires a looot of patience to watch it, but the 1st time I saw it in the cinema, I knew my money was well spent.
I would recommend watching:
Ocean's 11 and Ocean's 13 - 11 is the best, but 13 is alright, 12 is kinda "meh".
Hangover - you will be rolling on the dormeo orthopedic laughing your ass off all movie long
A clockwork orange
Curious case of Benjamin Button
..and of course Fight club
If I would make a top list Pulp fiction and Fight club would definitely be at the top - can't even decide which one is nr1 and nr2, they are both ingenious. (The book Fight club is a lot better than the movie though, perhaps Pulp fiction takes 1st )
The shining - still the best horror movie ever made, watch it in the dark, you will be freaked the fk out
Also check out Underground and Black cat, White cat - The 1st is hilarious at 1st, toward the end, though, getting pretty serious, however, Black cat, White cat - comedy throughout and finishes wonderfully with something extremely funny happening
