I came within an inch of seeing this one at Fantasia last week. It was playing on the day I arrived in Montréal, and I got there about 5 minutes after the movie had started

Some of the random people I chatted with during the festival had seen it, and they had nothing but praise for it. Apparently it's pretty damn funny, and a much better (and less annoyingly "hip") spoof of slasher flicks than Scream.
I'll have to catch it on DVD.
