When you've seen as many cop movies as I have, they become pointless. Sure, there are exceptional ones, like LA Confidential, but most end up being more like The Bone Collector, which is to say, the same old thing. Few of them try to really be mysteries, which means have real clues and require looking at situations from different angles. This movie has those things. Like every other film, it is about a detective trying to catch a killer, only this one is smart about it. Clint Eastwood is the detective, and he's a cool actor to watch, but this movie is not about acting. It is not about characters or dialogue or atmosphere or anything other than the mystery. Luckily that mystery is superb. Very Very smart twists and ways of figuring things out make this a clever little film. Much better than anything I've seen Eastwood in in a long while. It's all about the writing.
