“Deviant Behavior” (0 stars out of four) was a repulsive horror thriller about a seedy private eye (Eric Rodrigue) who is drawn into an underworld of murder, torture, and depravity and doesn’t know if he can morally or psychologically get himself out. Film is as disgusting and sleazy as the world it’s showing but also stupid and boring and terribly made. Rodrigue’s one-note performance (and unlikeable character) is no help. For a more inceptive and non-exploitive look at similar material, watch 1999’s “8 MM” instead.
