Four stars (R)
One of the best movies of 2007. Ben Affleck directs his younger brother Casey (who is excellent) in a striking mystery built around the disappearance of a 4-year-old girl and set in the working-class Dorchester neighborhood of Boston. The smart, melancholy tale of alliances, betrayals and ethical dilemmas grabs you and holds you all the way through. After the movie, you can argue with your companions about which character was right in the climactic confrontation. I love when movies give you something to chew on. 115 minutes. DVD INFO: Includes a commentary track with writer/director Affleck and writer Aaron Stockard, deleted scenes and two featurettes.
