A lot of great choices. Some others that I may have missed on lists, but I can watch over-and-over-and-over:
The Big Lebowski (I know...shocker)
The Godfather
Jaws
Empire Strikes Back
The Outlaw Josie Wales
Pulp Fiction - Get on it, UGLI!
The Shawshank Redemption
The Usual Suspects
L.A. Confidential
Almost Famous
Fight Club
Zombieland (It's very re-watchable so shut up)
This is probably the anti-Colton list, with all the R-Rated movies, but they're great movies.
I've actually seen edited versions of nearly all of the R rated ones. My comments on your list:
Big Lebowski - great movie, not quite "perfect"
Godfather - agreed, perfect
Jaws - didn't do much for me
Empire - perfect
Josie Wales - not quite perfect
Pulp Fiction - haven't seen it, will add it to my "to watch" list (edited version)
Shawshank - just a notch below perfect. but on another day I might call it perfect
Usual Suspects - same comment as Shawshank
L.A. Confidential - I'm pretty sure I saw it (edited for TV) a while back, but I can't really remember it
Almost Famous - haven't heard of it
Fight Club - haven't seen, no real desire to watch it
Zombieland - same comment as Fight Club
