It doesnt matter. Horror flicks get R ratings for gore, language and sexual content. These three things are not necessary for a good horror movie, but they help cover up the terrible story most of the time. PG-13 and R rated horror movies can be just as bad or just as good as each other. it all depends on the subject matter. Unless of course you are a gore connoisseur like myself, then R is the only rating worth watching. 🙂
