Old Boy may have been the original, but John Wick made the single killer massacre a box office staple. The latest to join the bloody gang is Bill Skarsgård, who has buffed up to play “Boy,” a deaf mute who’s whipped into shape by a shaman to wreak revenge for the murder of his parents. Once the stream of violence starts, it’s pretty much non-stop mayhem. However, the nervous camerawork and muddled direction often make the action a blur. There are a few cool moments of fight choreography, but mostly it’s a lot of havoc without much else. The attempt to add an emotional element doesn’t help. There’s basically nothing, except maybe for Michelle Dockery’s juicy villain, that makes this film more than a blur of blood. NOTE: Stay thru the credits for a final moment. (2 / 5)
