Query: well-made thriller

This is a smart, witty, and extremely suspenseful thriller. It's not as intricately plotted and sophisticated as some of Dahl's other work, but it's not supposed to be. It's more of a thrill ride, a teen horror movie, and a very effective one. Steve Zahn is very good--Fuller is funny and kind of charming, but you want to punch him. As an aside, I really wish people would not waste time reviewing trailers on this site. Anyone who thinks you can judge the quality of the movie from the trailer must not go to the movies much.
