Harry Brown: quite literally Gran Torino on crack. Make sure your grandma isn't around for the first five minutes alone.

Paddy Considine is a director who's good at this sort of stuff. Dead mans shoes and Tyrannosaur are both great if not pretty damn disturbing.

Does Kill Bill count? It's certainly violent.

Other than that I'd have to go with Blood Gun Death mutilator 3: Revenge of Bulltetface.

Pokemon the first movie.

And here I was thinking you couldn't possibly be more terrifying.

The Devil's Rejects was pretty gruesome. Cannibal Holocaust. The Human Centipede 2..terrible movie. Those are the worst I'd have to say, mostly cause of the realism at least with the first 2.

I wouldn't say Human Centipede 2 is a realistic movie, but I agree with the others. August Underground's Mordum is the worst I've ever seen, and I do not wish to see anything equivalent or worse. It ruined my taste for shock films forever.

Err I forgot to mention that I was excluding that one, yeah I don't think it's realistic either..except some of the things the guy does to people..especially the knee part. That felt pretty realistic..I had to say ouch.

I think it is time to end this thread. Many of the movies being discussed do not fit with the forum rating.
