Horror Films are unsettling films designed to frighten and panic, cause dread and alarm, and to invoke our hidden worst fears, often in a terrifying, shocking finale, while captivating and entertaining us at the same time in a cathartic experience. Horror films effectively center on the dark side of life, the forbidden, and strange and alarming events. They deal with our most primal nature and its fears: our nightmares, our vulnerability, our alienation, our revulsions, our terror of the unknown, our fear of death and dismemberment, loss of identity, or fear of sexuality. Whatever dark, primitive, and revolting traits that simultaneously attract and repel us are featured in the horror genre.

Horror films go back as far as the onset of films themselves, over a 100 years ago. From our earliest days, we use our vivid imaginations to see ghosts in shadowy shapes, to be emotionally connected to the unknown and to fear things that are improbable. Watching a horror film gives an opening into that scary world, into an outlet for the essence of fear itself, without actually being in danger. Weird as it sounds, there's a very real thrill and fun factor in being scared or watching disturbing, horrific images.

Horror films, when done well and with less reliance on horrifying special effects, can be extremely potent film forms, tapping into our dream states and the horror of the irrational and unknown, and the horror within man himself. (The best horror films only imply or suggest the horror in subtle ways, rather than blatantly displaying it, i.e., Val Lewton's horror films.) In horror films, the irrational forces of chaos or horror invariably need to be defeated, and often these films end with a return to normalcy and victory over the monstrous.
