The music in Silent Night Deadly Night is pretty great too. Something about that movie just is fun to watch. I can't wait to watch Black Xmas. I've been trying to hold off to get closer to the Holiday but I don't know how much longer I can last. Scrooged has some horror elements and is also directed by Richard Donner who was one of the producers/directors from Tales From the Crypt. Far from a horror film but still great and worth mentioning.
It doesn't get much better than Gremlins with the combination of the Goldsmith score and Dante's direction. One of the more magical movies ever.
Last Christmas I ordered and watched the Burning, Sleepaway Camp, and of course Silent Night Deadly Night. I was obviously in a slasher phase but the funny thing is, now Sleepaway Camp and the Burning feel like Xmas movies to me.
