favorite shock factor horror movie?

Pulse another movie that just had the "WTH" factor.
 
i would have to say the stephen king movie the mist. I am a huge king fan i own every book he has ever written and the way the producer's took liberty to put a end on the movie that king didn't on the book was sickening. If any of you have seen this movie and have children you know why i almost puked when i saw it in the theater.

Ahhhhh Feast 1 2 and 3 are the most disturbing horror movies I have seen in a long time....a looooong time! lol I couldn't belive it when the movies ended...i had to just look at my husband and say...what the hell?!?!? did I really just see all that?
 
The scariest movie I have seen was Dead Calm. It was mostly suspense but really creepy.
 
There are so many! Texas chainsaw masc freaked me out (one of the original) where he stomped on the girls head and welll...you know
