This thriller gets the basics right: It has a great villain and is not weighed down by an excess of plot. Rather than treat the victim as a disposable means to an end, she is given full supporting character status.
Tennant's sadist-creep Cale is the film's strongest element. He is wily, sociable, attractive. He is deliciously hateable as a one per-center who delights in re-enacting childhood psychodramas with unwilling actors, kidnapped off the streets.
