I saw this as it was making its festival runs (our city had its first horror film festival this year) on Halloween. Great movie, a perfect homage to the slasher films of the 80's. And you gotta love the cameos in it (Robert Englund, Tony Todd and possibly others) as well as casting Kane Hodder as the deformed psychopath killer, Victor Crowley.
Overall, the most fun you can have watching people die this year.
