You know a really cool flick (at least I think so)? INTRUDER. It was directed by Scott "I'm Sam Raimi, Bruce Campbell AND Quentin Tarantino's buddy but I just can't seem to break through" Spiegel and was written by Spiegel and Lawrence Bender (Tarantino's producer). It is about the last night of a crew working at a grocery store that has just been bought out by a major chain that are terrorized by an unseen killer. It has Sam and Ted Raimi in it, as well as cameos by Bender and Campbell. I have the uncut version on VHS and it has some really nice gore courtesy of one of the first collaborations of KNB EFX Group.
Interesting note about Spiegel... a homeless Tarantino was crashing on this guy's couch when he was writing Reservoir Dogs and Pulp Fiction.
