Hmmm...I love Sleepy Hollow,Not the flm film,but the WAlt Disney short.It's really good,and when I watch it,It brings abck memories of being scaredwatching it as a child,which in turn,frightens me.I really really like it.
If you want complete blood/gore Ichi The Killer made me cry in fear like a little girl.
Edit: Watch E4 now,The countdown from 100 to the all time greatest horror movie is on,IT will show clips from horror films,I think these shows are great as it gives you an idea of wether or not you'll like the film that your friend thinks is so great.
