I saw this movie in the theaters when I was 16 with a friend. We sat through half of it before we were so freaked out we ran out of the theater. I slept with the light on for a week. I think what freaked me out was the fact there was no way to stop the ghost from killing you. I watched the whole thing when it came out on video with my older brother. He made funny commentary throughout the movie that helped me not to be so scared. Because of how scared I was when I saw it, and I was 16, I really don't think it's appropriate for 15 or younger.
