The Vanishing

For all his intellectual credentials, Hannibal Lecter was just a pretentious dandy. The true thinking man's psychopath is Jeff Bridge's "Barney" in this story about one man's (Kiefer Sutherland's) obsessive, years-long search for a girlfriend who disappeared during a vacation. Barney is also perhaps the nerdiest, most passionless movie psycho ever, and for all these reasons one of the most terrifying. This film is light on gore and action (some might say "slow-paced"), but it is a disturbing look at the "banality of evil." I'm told that the original Dutch film of the same name is far more disturbing than even this.
