“Behave” (*1/2 out of four) was a clunky horror thriller about a group of friends (Washim Abdul Gafoor, Eleonara Bindi, David Bourne, and others) who are reeling from the death of one of their friends and go to a villa in London to party and let loose when a psychopathic killer follows them and havoc breaks loose. Nothing you haven’t seen one million times before and you won’t see again done better; the killer dresses like Ghostface and the movie pays homage to (i.e. rips off) “Scream.”
