As a horror movie buff, I usually ask this question of my friends to see if they have watched a good horror that I may have missed out on. Let me know what movie has sent chills down your spine and ones that you would definitely recommend for others to see.
Hmmm.... I can't think of the scariest horror film I've seen off the top of my head. I think you definitely get a little desensitised over time. When I was a kid Candy Man was one of the scariest films I remember watching.
Recently I really enjoyed Woman in Black. I think I actually watched it on your recommendation Gen. :)
I can't watch horror movies anymore - when I was little my big brothers let me watch movies like Nightmare on Elm Street and Friday the 13th with them and they scarred me for life! I still can't see an image of Freddy Krueger without a moment of terror...
