The Wrestler (2008)
Extremely good.
This is just the kind of movie that stays with you. Hours after, you'll still be thinking about it (even if you're not sure why).
Mickey Rourke is just plain incredible. The role was just made for him. I still wish he had won the Academy Award for best actor.
Marisa Tomei did a great job too.
Its rare that something could be so fundamentally sad but not really make you upset.. just.. bothered.
