I thought the final destination movies were kinda sick and gory. the first one when sean william scott died but more in teh second one when the boy got hit by that thing that fell on him, when his moms head got ripped off by the elevator, when the barbwire fence sliced that guy in thirds, when the ladder imapiled the guys eyes

I found Reservior Dogs to be the sickest film. I've seen almost every movie ever, and 'Dogs has to be the most disturbing - I'm thinking the whole Mr. Blonde torture scene here.
It's amazing considerring there's no limbs, brains or anything, just blood. It's all the more realistic, and disturbing because of it.
OTT films like typical horror movies tend to overdo the shock factor and just numb you to scenes you should normally find horrible - but Reservior Dogs builds up Mr.Blonde and makes you like him, then the sick freak does THAT to that poor cop.
