I'm sorry you feel that way Jim. yes the old horror movies were great but today they wouldn't scare anyone, including myself. Do you really think a guy covering up his face with a cape and looking into his eyes is scary today?. Maybe for you but not for the masses including myself. As I said, yes, when i was a kid, I was scared because we didn't know any better.
Plus, not all horror movies, or scary movies are blood and gore as you think. Movies like the Blair Witch Project just scared the hell out of me and there wasn't one scene of blood, gore, no one shown getting killed but it was one scary movie.
And a movie like Psycho, where there was some blood although it was chocolate syrup) and knifing, was 10x more scary than any Mummy movie.
Movies like Jaws, where there was also a small amount of 'blood and gore' as you say, was one of the scariest movies ever. And the movie voted the #1 horror movie of all time had NO blood and gore but a great story and a terrifying plot, The Exorcist.
If you think the early horror movies were scary, OK, maybe when we were kids, but today's good horror movies that are well beyond blood and gore, are truly 10x more scary than anything from the early days of movies.
