Man, this list has a lot of depressing movies in it:
All Quiet On The Western Front (greatest war movie ever)
Apocalypse Now
Deer Hunter
Usual Suspects
Cool Hand Luke (well, the bad guys sort of win, but not symbolically...)
American History X
One Flew Over the Cuckoo's Nest (the book was better though)
Paths of Glory (i guess)
Spartacus (i started thinking Kirk Douglass I guess.) man I love this movie.
Das Boot (yeah, a lot of war movies...)
The Killing (well, they're all kind of bad guys, but they all die at the end... not sure. probably the same category as Reservoir Dogs)
Amores Perros (ok, that movie is just sad)
Yeah, watch these movies if you want to go emo and be all depressed for a week or so.
