Those who gave it a negative review were right on the money

Rating: 4/10 (7 February 2015)

John Wick is some super assassin who left the biz and got married. His wife dies of cancer, he runs into some Russian punks we decide to beat him up, steal his car, and kill his dog. John decides he's going to get revenge and spends the next 90 minutes killing everyone in his path.
The action is decent, but we've seen it in Jason Statham's movies already, so nothing terribly new here.
The film hints at some secret underground society of assassins, but totally drops the ball by failing to flesh any of this out. Ahh, what could have been.
Not the worst movie I've seen, but it's still pretty weak.
