I watched it a few days ago and really enjoyed it. But I can see how some might not. I don't want to give away much but it can come off as "what was the point?" after watching, but IMO, that's the point. Fassbender's character is not exactly a reliable narrator. If you look at him as having a higher opinion of himself and his skills than who he actually is, it makes sense. That said, I think if you are a Fincher can already, you'll enjoy it. There's an amazing, brutal, fight scene that is almost worth the viewing alone.
