Yesterday night I re-watched The Texas chainsaw massacre (1974),
and its still freaking me out like the first day.

It has that disturbing aura which actual films don't have, even the worst slasher ones.
Its so real, dirty and unpleasant.
It also has one abrupt ending out of the blue.

I actually don't like the chainsaw massacre, I just watched it because I am a masochist.
