Since the OP was inspired by John Wick, and I just saw John Wick, I have to add it to the thread. It's violent, cool as shit, and easy to see action in every scene.
When there is gun play, it is efficient and brutal. Where there is karate, it is to the point and brutal. When there is MMA inspired fighting, it is on point and nasty. There is zero wasted motion in any of the action. Everything is done with intent, purpose, and efficiency. The action deserves and lives up to the R rating of the movie. It's the most bad ass main character in a major film in years. The action is really wonderful through out the whole movie.
