[I_Still_Know!]

Most distubing movie to me was The Texas Chainsaw Massacre (original).

In particular it was the scene where they have the girl leaned over with her head over a large bucket and they are trying to get that filthy grandfather 'thing' to give her a good whack in the head with a hammer. And they are all cheering him on while she is screaming her head off.

I know it is just a movie but I hate even thinking that humans could be capable of doing those kind of things to another human being.... for pleasure.
