Here some of my thoughts about this list:
Texas Chainsaw Massacre: My fav horror movie, would have been a mutiny if this film didn't make the cut.
Halloween: Good Stuff.
Seven: I thought these were supposed to be HORROR movies!?!?
Silence of the Lambs: Same as Seven.
Rosemary's Baby: Zzzzzzzzzzzzzzzzzzz
The Thing: Glad to see this one make the list, underrated horror flick.
Evil Dead: Classic.
Carrie: Another classic.
An American Werewolf in London: Didn't really care for it.
Omen: I still need to see this one, I've heard great things about it from horror fans.
Lost Highway: See Seven, Silence of the Lambs.
Moon and Duran, I agree Audition was a wicked flick and should replace one of the above 3.
No High Tension??? Blasphemy I tell ya!
I woulda put Scream in here somewhere, it started a whole new genre of crappy horror.
