This is kind of an odd film. It does a reasonably good job of being engaging, with a slick directorial style and nice tension in a lot of scenes. There aren't nearly as many action scenes as the trailer would have you believe, but those scenes are satisfying. Fassbender plays his part well, although his character doesn't require much dynamic.
But I doubt I'll be thinking about this much a week from now. The story itself seems simple enough that you would think it would be hard to screw it up and yet how we get from one scene to another is rarely explained. The entire film essentially consists of him tracking various people down but how he even knows where or who they are is almost never shown. The conclusion is also a bit nonsensical given what we are taught about his character. Furthermore, the entire affair seems like a missed opportunity: the fact that our protagonist doesn't change at all ends up feeling like the film really wasn't "about" anything. Of course not every film has to be about something, but they are usually more memorable when they are.
