John Wick is an ex-hitman who flips when someone kills his dog. Yes. A dog that's a farewell gift to him from his just-died girlfriend. Oh, and yes, they also steal his beloved Ford Mustang.
Reason enough for John to come out of hibernation and let mayhem reign over town, taking out half a million henchmen, while going for the dog killer. And his father. And a bunch of other assorted contract killers.
May be a decent watch for Keanu Reeves fans, but at 101 min, it was about 100 min too long for me.
