Most Helpful Guy
Many people have a strong desire to "experience" fear and danger - but in a "safe way" (without any real danger to themselves), and scary movies are one way of doing that. It's not a lot different than going to an amusement park and riding the thrill rides - which replicate REAL-WORLD dangers in safe, fun ways.

I watch them because it makes reality look much more appealing... helps me cope with an imperfect life.
