I love the very ending too. The camera zooming out of the house. I absolutely love Horror movies that have great Christmas atmosphere and this is up there with the best. Black Christmas, Gremlins, Silent Night Deadly Night. Zemeckis' episode in Tales From the Crypt in 1989. I also watched Tales From the Darkside's episode Seasons of Belief. If you haven't seen it, definitely check it out.
Did anyone see the American Horror Story Christmas episode called Unholy Night? Man now THAT is what I've been looking for. About 45 minutes of great horror mixed with creepy Christmas music. One of the best Horror related episodes or movies I've ever seen.
Watched the new Silent Night tonight. I can't understand why they are calling it a remake because it has little or nothing to do with the original Silent Night Deadly Night. That being said, it was a pretty good slasher and would watch it again
