Instant cult classic. Highly recommended. I thought it was going to be another "B" horror movie. But it was far from it. It is actually a really smart movie, with great acting, and has an agatha christie murder mystery style while throwing in some of the most absurd over the top hilarity capped off with funny one liners by original "Bad Kid" Judd Nelson who plays the headmaster. Do not think this is a movie to watch late at night. I think the people who rate the movie poorly probably are expecting a slasher without demanding much thought from the viewer. On the contrary, it demands your attention as details are sprinkled throughout as you try to figure out who or what is behind the killings. Oh...and the soundtrack is bad ass!
