I'll pass for now. The only horror movies that have a chance at scaring me are the ones that really get into your head with the psychological fear but also aren't afraid to show you lots of nasty gore. It's the characters' sense of hopelessness rather than the explicit violence that gets me in this genre. Saw and House of 1,000 Corpses are good examples of what I'm talking about.
For this Halloween though, just got Rob Zombie's Halloween, that was awesome, better than the original even. Now I'm working on the Hannibal Lector series, started with the prequel Hannibal Rising, then Manhunter, next up is Silence of the Lambs. He's gotta be one of my favorite movie villains now.
If anyone sees Paranormal Activity post a review. It may well creep me out, I had an experience like that as a little kid and the commercial looked pretty similar. And the Blair Witch Project was worth watching once, it's a bit creepy if you can stop reminding yourself it's just a bunch of kids running around the woods with a shaky cam.
