Mystic River.
I think i've developed a weeee bit of respcet for Robbins.I'm too lazy to go back and check who said it (I think it was Aaron),but yes,Penn's performance in 21 grams outshines his perfromance in Mystic River by a country mile.Oh and Bacon is a better actor than i thought.
Overall,excellent movie.My only complaint is the fact that Emmy Rossum didnt have a nude scene.
