Katie Holmes is well-cast as an intellectual college student in this intellectual thriller, a strange bird of a movie to sit alongside the current batch of "teen" horror films (did you know that in this one the students actually - gasp!- study?). Admittedly it moves at a measured pace (some would say "like molasses"), and doesn't really take off until the last 2 minutes or so (!), when it presents a final twist which I, for one, did not see coming, and which saves the entire picture. All through the film you get the feeling they have something to show you at the end, and indeed they do, but perhaps they shouldn't have waited so long to get there. Excellent score and cinematography. (**1/2)
