There is no future in horror films, since "horror" is now going to be defined as how much gore you can squeeze into 120 minutes.
I was reading an interesting article today in a list of top horror movies of all time by a specific critic. He was discussing the original "Psycho," and hit the nail right on the head:
"Director Alfred Hitchcock’s “Psycho” isn’t just The Great Slasher/Haunted House film of all time, it’s also one of the greatest films period. And what’s most remarkable is that though the story of Marion and Norman and Mother is now a full half-century old, there is no movie-lover walking around today too “sophisticated” to be knocked over by it. No matter how many films, horror or otherwise, you might have seen over the course of your post-modern lifetime, if you walk into “Psycho” cold — unaware of Hitchcock’s treasure trove of groundbreaking surprises — your jaw will still hit the floor at the precise moments the then-60 year-old director wanted it to."
The famous shower scene with Janet Leigh is still one of the most frightening things ever filmed, yet there's not even 1/100th of the gore that you see in today's torture porn flicks. Ironically, Janet Leigh was famous for this scene, and her daughter, the wonderful Jamie Lee Curtic, got her start in films in the early "Halloween" movies, the first of the real gore slasher flicks. (even those are tame by today's standards).
Personally, what I fear is that the amount of blood and torture in these movies is desensitizing people to the real horror of real violence and torture. They see some much of this stuff, nothing is left to the imagination, and the real horror of such things is then reduced to some cartoon-ish screenplay. And if they're not sensitive to it when watching a movie, we can't wonder if they watch scenes of real death and horror (like 9/11 or some terrible natural disaster) and just shrug in boredom.
