You will understand why the tagline for this show is Don't Set Him Off when you watch this movie. John Wick (Keanu Reeves) takes the leading role in the show. He is an ex-hitman who is now on the mad run to hunt to track down the gangsters that took everything from him. Which is his, dog, yeah you read that right, his dog. The dog was the final token for him from his dead wife and some gangsters just decided to kill it. Stay classy stupidity.
If you enjoy watching Keanu Reeves back on his old role. More action than words then this is the correct movie. He is a train assassin with superb skill in shooting. Unfortunately, the hand-to-hand combat was weak on his part but overall a pretty entertaining movie to watch. It feel as though I am watching Max Payne in action.
TL;DR: Research before you rob someone and don't kill people's dog.
