"If movies are the dreams of the mass culture... horror movies are the nightmares"-Stephen King
This simple question causes a lot of (sometimes dishonest) debate. While it is not reasonable to expect everyone to have film genre theory under their metaphorical belt, it is still frustrating to hear people spout problematic criteria that falls apart in microseconds under the most basic scrutiny. I'll be critiquing some of the more nonsensical takes before ending with a working definition. Horror filmmaking is rooted in stories, folk tales, tall tales, and any other storytelling intended to scare, shock, and thrill listeners. It is meant to repulse us, often with a central villain, monster, or threat that is often a reflection of the fears being experienced by society at the time. This person or creature is the monstrous other, a term that refers to someone that is feared because they are different or misunderstood. The Horror genre changes because society changes.
