I'd give this 4-1/2 stars if I could. The first John Wick is 5, and for me set the standard for 5 for an action movie. There wouldn't be many 5s.
This movie has some great stuff, and Reeves is great again, and so are the supporting players. But there are one or two grotesque failures of logic or sense, given the world of this movie. Also, there are a couple of points where I feel like I'm in a video game.
But, jeez, the movie is still really good, and the opening sequence is absolutely awesome (and loony) fun.
