I know this isn't a classic yet, but it still gives me fond memories of the time when it came out. Freaky upper-class people, who have a booby-trapped house. The mom looks like a dude. The old dude dresses up as some sort of BDSM gimp. And of course, all the zombie looking people in the basement and under the stairs that nobody knows about. In a way, it was also a teenage romance type of movie. I know it sounds stupid, but I really enjoyed it for some reason. I must be crazy.
