Could you name the scariest movies ever made?

I agree with you when you say that The Exorcist and Halloween were some of the scariest movies ever made. I didn't see Night of the Living Dead or The Texas Chainsaw Macre. I thought that the Shining was a very good movie, but not at all scary. Just a little bit creepy. I'm not easily scared by movies, but I will say that The Sixth Sense definitly gave me the creeps.
