They're long, boring and skew good moral values. You won't find horror movies skirting the moral issue. They attack it like a fist slamming through a guy's head. Think about it. Anybody who commits an egregious, sinful act is punished.
Sex is a perfect example.
Those who have sex, especially unprotected, wind up filleted or saut ed. Same with drugs or booze. That's why it's always nice to watch a horror movie with a beer in hand. I have compiled a list of some great horror movies for this festive month. Some are well-known, others maybe not so much.
