Who new that Ben Affleck would be such a good director/actor, but, he is both!
I've never been to Boston, but I imagine the characters in this movie to be picked right out of the white pages of the phone book for the area.
Go see it! You'll have to wear your best green outfit and maybe drink some green beer to understand the heavy irish/Boston accents, but, it's so cool to hear what's left of a sound that is local to a weary city. Missing "r's" never sounded so good...smile.
