Just saw it and I agree with everything broadway86 said.
What a fun Halloween movie! One of the best I've seen in a long time. It was so clever and had a few genuine surprises. Dylan Baker and Brian Cox are wonderful. Highly recommended for genre fans or anyone looking for a good flick for the holiday. Excellent!
The Hills Run Red was good. Better than Trick r' Treat, actually, IMO.
I did enjoy both movies, but let me just say I'm not thrilled, no pun intended, with the release of horror movies this month. The selection is usually a lot better.
