Oh yeah,

Trilogy of terror with Karen Black, and that scene at the end... that was heavy stuff. Now though, those prune headed little demons make me laugh just to think about them. 70's made for TV special effects have not dated well, for sure.

How about another with Karen Black - Burnt Offerings. Not a slash 'n' gore horror movie, but a great haunted house story with a shocker of an ending, well, at least the first time you see it.

Have to agree with previous posts about Deliverance. That was the kind of movie that makes you cringe, because the things portrayed there could actually happen. And that
"squeal like a pig boy..." is about the most sickening bit in the whole movie.

I just thought of another one that spooked me - I think it was it Hellraiser. The one with the guy who had all the pins stuck in his head in a perfect criss-cross pattern and a whole cast of other gortesque perverts. That was some messed up sh....tuff.
