John Wick is a simple revenge story with a lot of action scenes. Dialogue is kept short and simple. Because of this, pacing is really good. Cinematography and fight choreography are great; action scenes are filmed with minimal cuts and are satisfying to watch, although not really realistic. Music goes well with the action scenes. The world it is trying to build is interesting in its own way and probably a differentiating factor from similar movies. The acting is good, mostly carried by the other actors, while John (Keanu) does the shooting and is a character of few words.
