If you're looking for something REALLY scary to watch this Halloween, a website called StudyFinds claims to have found the five SCARIEST movies. They visited, and I quote, "10 of the leading expert websites", to see which movies are rated the most fright-inducing.
Here are the results
1. "The Exorcist", 1973
2. "Halloween", 1978
3. "Paranormal Activity", 2007
4. "The Shining", 1980
5. "It Follows", 2014
