My favorite horror movie, just in terms of movies in general, is the original Night of the Living Dead, hands down, because it's one of my favorite movies of any kind. Incidentally, I'm going to see a play adaptation of that tonight, which kind of disappointed me when I found out it existed, because I had hoped to be the one to write it.
My favorite creepy horror movie is probably Frailty. There really aren't that many horror movies that creep me out, though I still love them, but that one did. Great little movie.
I think the classic ones are much better than the newer ones. The ones from the 70s and 80s are less based on torture and pain than the modern day ones, and though the old movies often come across as lame and funny, I still like them more than their bloody modern day equivalents. I also find that some of the older films have a much better plot than the new ones. In general though, I guess I just don't really like horror movies.
I'm a horror movie freak. If you haven't seen John Carpenter's "Cigarette Burns" you must see! It's one of the most disturbing films I've seen in a long time. It only runs for an hour but wow. I too like the old films. One of my favorites is the original 1960 "Haunting of Hill House". I also like "Ghost Story", which I think was made in the 80's.
"Mulholland drive", by David Lynch. It is not really a horror movie to begin with, but that's one of the few movies that've stayed with me after the first viewing.
It's all so absurd, half of the movie you can't even guess what's going on. And then, when you finally think you're on to something; the plot takes a 360 degree spin for the worse!
To hell with the old saying; "Ignorance is bliss" It was exactly my ignorance that kept my pulse beating. I can't think of another way to describe it. Guess its one of those movies you'll just have to watch, to be able to relate?
