"Black Mass" is exactly what you expect from a gangster film. Violent and filled with a great deal of moral questioning. This film is not afraid to throw the viewer into a world where everyone is corrupt; there is simply no one to provide a moral heading or hope. This might challenge audiences, but certainly elevates the material in many respects. Depp's performance in particular is the standout while the film's propulsive pace helps keep the story organized and clear.
