AMC is doing a thing called "Monster Fest". It's pretty badass in that they're showing all horror, all the time. I've seen classic Frankenstein and Dracula horror movies (black and white) to Amityville (I, II, and III) to Dr. Giggles...
The Omen (I and II)
Silverbullet
Scream 2 (YUCK)
There is so much more too!
