Comportamiento perturbado

In Cradle Bay on Crescent Island, football jock Andy is parked with a girl. His demeanor turns and kills her. Then he kills a cop and Officer Cox (Steve Railsback) lets him go. Gavin Strick (Nick Stahl) watches from afar. The Clarks from Chicago arrive in town after losing the oldest son. Gavin befriends Steve Clark (James Marsden) who explains the school is ruled by a clique called Blue Ribbon. Steve is taken with edgy girl Rachel Wagner (Katie Holmes). Dorian Newberry (William Sadler) is the school janitor and rat catcher. Steve and Gavin discovers the parents working with Dr. Edgar Caldicott (Bruce Greenwood). Gavin is picked to be the next candidate by his parents.

I like the Bodysnatcher feel to the story setup. There are probably too many kills too early and it probably effected the ending. The actors are all good in their roles. However the movie ends badly. I think the writer couldn't figure out a clever way to end the movie. It's too bad because the movie seems to be set up for a tense thriller. Instead, it's done without any finesse and it's unsatisfying.
