Denzel was good, but not Oscar good in my opinion and the movie was average. There was no ambiguity with his character. He was just bad. I would have enjoyed it more if he had some redeeming qualities. He did those bad things, but he also did some good stuff. Forces the viewer to reconcile how they feel about the character. The Shield did that well with Vic Mackey. He was bad, but he did a lot of good police work. So there was a grey area with him.
