I was impressed by the acting from all parties. We sense a lot of their backstories in subtle actions, not obvious dialogue--even the most shallow characters are portrayed with complexity. By far the most unexpected and impressive performance is Amy Ryan's depiction of the missing girl's drug-addled mother. She stole every single scene she was in. But even the best acting can't hide bland, blunt dialogue, which this movie had a surprising amount of. Still, the writing wasn't all that bad. The story was constantly fascinating, both in terms of plot and ethics.
Most of the problems in this movie lay in the editing. The story's two-part structure hurt the overall pacing of the film. The editing of each scene felt really jumpy, and I think Affleck overdid the grainy, two-second flashbacks. Also, the rapid-fire Boston accents (and even one Haitian accent) were difficult to follow and made the mystery even more confusing. Overall though, Gone Baby Gone is an intriguing film and succeeds in being much more than a simple police procedural.
