So many great ones to choose from. I remember first seeing A Clockwork Orange in high school after one of my buddy saw it and he kept telling me that I had to watch it. I did, and I was blown away. The first time I saw it, it didn't really frighten me, I think because I was just trying to understand it. The more I saw it though, the more it started to scare me, and to this day it is still one of the scariest movies to me.
The whole list, aside from a few IMO are great, but I'm going to say The Shining. He really hit the ball out of the park on that one.
