We crave chills. It's why we get a rush when we see Jason take his axe to some unsuspecting teen in "Friday the 13th" or why we can't seem to look away when Carrie, dripping with pig's blood, sets her high-school class on fire. The real question is: why do we pay for the pleasure of being scared? On this, there are various schools of thought. Some believe that fans of horror (be it movies or books) don't actually experience fear, but are excited instead, while others believe that people are willing to endure the terror because they know there is no real threat, that they are essentially safe. Still others feel that moviegoers are willing to be scared in order to feel a sense of relief at the end. Whatever the reason, movie studios like Seven Arts Pictures, a Los Angeles-based indie movie production company, are counting on customers who are willing to pay to be frightened, by releasing a horror movie like "Night of the Demons." In the movie, three friends attend a party held in a mansion where, years prior, six people disappeared and the owner hung herself. "We think that people have a fascination with the dark side, " said Peter Hoffman, CEO of Seven Arts. "So even though a horror movie might be illogical on an intellectual level, people still like to be uncomfortable on an emotional level. It's about people facing their fears," he added. This explanation makes sense and explains why we keep creepy haunted houses busy at Halloween, why we tell ghost stories around the campfire and why we turn out for horror movies like they were giving away free popcorn. It's because we like it.
