“Rattlesnakes” (*1/2 out of four) was a toxically unpleasant melodrama about a successful therapist (Jimmy Jean-Louis) who is held hostage by 3 vengeful husbands who are convinced he has been sleeping with their wives. While physically confined to a chair, he attempts to mentally and psychologically turn the tables on them. All-too-obviously based on a play by Graham Farrow but what worked on stage fails to transpire to film. Since none of the characters are likeable, it’s difficult to care about any of them or their plights. Story- and characters- are more than a little reminiscent of 1997’s “Suicide Kings” with Christopher Walken.
