Movie: Gone Baby Gone

Ben Affleck's directorial debut, staring his brother Casey Affleck as a young, inexperienced PI seemingly in over his head in trying to locate an abducted 3-year-old girl. This gritty movie has enough twists and turns to satisfy most viewers.  Deb and I watched his for an hour before we finally figured out we had seen it before, but it still took us a while to remember most of the ending.  Is doing the right thing always the right thing to do?
