John Wick is an excellent revenge action movie that raises the bar with its excellent lighting, cinematography, and martial arts displays from Keanu.
Mr Wick spends the rest of the film getting even with a mob boss for the actions of his son who killed his dog and stole his car. As far as the plot goes, its pretty simple but there is a lot of depth to the world.
Reeves displays a decent amount of acting range here, but his real talent is bringing bad guys down one headshot at a time. Its glorious to see him smack a guy over the head, hold him down while reloading, and then take him out.
The best thing about this film is the lack of shaky cam-- you can see all the action happening clearly. This is made possible by the dedication of the actors in their martial arts training.
