The Shining. The one with Jack. Not the douchebag off of "Wings". Which, btw is one of the worst shows of the late 80's... right along with "Coach". I think back-to-back reruns of those shows would be playing in my own personal hell. Maybe The Shining isn't horror. I'll have to think about that one.
I dont know if I have a favorite one. PumpkinHead had it's moments. I like the original Night of the living dead, the black and white one, where everyone dies. The original chainsaw massacre Ghost dad, by far.
