Basically people who love horror movies are people with boring lives. They want to be stimulated, and they need to reassure themselves, because when a really scary movie is over, you’re reassured to see that you’re still alive and the world still exists as it did before. That’s the real reason we have horror films—they act as shock absorbers—and if they disappeared altogether it would mean losing one of the few ways we have to ease the anxiety of the imagination.
