“Cocaine Werewolf” (* out of four) was a howlingly awful horror show about a group of friends (Brice Kennedy, Yolie Canales, James Carolus, and others) filming a horror movie of their own in the Pennsylvania woods when a cocaine-infused werewolf shows up and prowls on the set and kills them off one by one. Yet another movie inspired by the bewildering success of “Cocaine Bear” but terrible acting and filmmaking make this a real bad trip. You’ll have more fun (and a lot more scares) attending an N.A. meeting.
