Having only just barely managed to sit through several of the movies this parodies (Final Destination, Cherry Falls, etc.) I would say that most of the time it is does a pretty good job of poking fun at them. While it is very hit-and-miss in places it was a lot better than I expected and many, many times funnier than Scary Movie. Most of the jokes are one liners and while some fall flat enough of them are funny that you end up laughing quite a lot.
