What's the SCARIEST movie you've ever seen?

I have to say Blair Witch just didn't work for me. Before blair witch went to the cinemas, I saw a direct to tv film that was about alien abductions that was exactly like blair witch: same found tape concept, shaky cam, etc. The only "found tape" film that worked for me was Cloverfield. Well done that one. Also loved Sixth Sense. Great little thriller. It is a ghost story but I don't know if it should qualify as a horror movie...

I like to think that there is a category between thriller and horror. The sort that just chills you... Sixth sense is like that, the scene where he gets locked in the cupboard at the birthday party is very chilling.
