This.
I was very excited to see it since I grew up in Boston and lived their for 20 or so years...affleck hit the nail on the head with the boston attitude though, it was spot on and most of the people who saw the movie (if they've never been around boston) probably didnt pick up on a lot of the subtleties, thats one part where affleck excels - he absolutely gets the people around here
Also the locations were great, if your from the area your able to recognize teh charlestown football field, the diner near the 93/rt 1 interchange, the harvard square scenes, and of course bunker hill and the fenway scene
overall it was really good, although it lacked the action that made the trailer so enticing..it was too much of a love story
