Ben Affleck’s follow-up to Gone Baby Gone finds him sticking with his roots, again setting the film in a desolate part of Boston. But there is nothing to heavy here, just a crackling, straightforward crime caper, part Heat and part The Departed, with a few nice twists, solid performances and Don Draper as the dogged FBI agent on the trail of a Boston robbery squad. No great shakes, but efficient, smooth and entertaining. Best, Affleck smartly plays the lead as monochromatic, keeping his lifting to a minimum.  Bonus:  Blake Lively plays trashy and she carries it off!
