I loooove scary movies! There aren't many that really scare me, but the ones that do, they do it good
The last one I watched was Silent Hill, and I loved it! I watched it with some friends and they were all scared during the movie and I was like "it's not that bad" but then when I got home and had to go to bed.. I had a hard time!
And the ones that scared me big time, so bad I get chills just thinking about them, were IT, The Ring and The Grudge. Those three really got to me!
As for books, I loved IT and another one I can't remember the title, but they made a movie and it was about this couple and the woman (Rosemary) gets pregnant by the devil.. that one was scary
