It was a rather unusual film. As it continues and it appears a bit ordinary but then what is happening seems rather silly. But gradually a very strange story emerges as the killer doesn't seem the usual at all. I don't want to give away the end but everything makes sense, also I'll mention that the song at the final credits is Norman Greenbaum and Spirit in the Sky. It even made me smile. And many will be very pleased to see Christopher Lloyd, specially, I imagine.
