My Favorite Bad Endings

Haven't a lot of time on my hands, I decided to go through my DVD collection to find the movies I own with the best bad endings. Turns out, I have more movies with bad endings than i thought, I guess I prefer a bad ending to a good one (who doesn't?). So here are my top 15, in alphabetical order:
American Beauty
Antichrist
Boys Don't Cry
The Hours
I Am Love
Irréversible
Milk
Monster
One Flew Over The Cuckoo's Nest
Paradise Lost 2: Revelations
Requiem For a Dream
Revolutionary Road
Silkwood
There Will Be Blood
The Wrestler
