This film is very much in the style of Jack Reacher, except the principle character Terry Richmond (Aaron Pierre) is more principled in that he doesn't like to kill. The movie itself is basically your classic "bent cop" story with Richmond exacting justice for the injustices he and others have suffered.
I would definitely describe it as a slow burner (which I like) as to many films these days seem to try to appeal to the "want it now" generation of instant action and violent gratification.
Good acting throughout and well worth a watch. I certainly think Aaron Pierre is a future superstar...
