Horror movie research

So I took the time to do some research in the horror genre and realized that most movies are catered to the younger audiences such as young adults. Although most of horror movie ratings are R by logic.
I did some research regarding the highest grossing horror movies to see what direction we could take on the project and I stumbled across a Forbes article listing the top 25 grossing horror movies of all time. I’m only going to show the top ten seeing as they are far more important.

As you can see from the post above, the horror movies that bring in the most amount of money are movies that  are relating to the supernatural and to the unexplained. 6 out of the 10 films in the top ten deal with either ghosts, demons, of Clowns that are from another galaxy.
