Yes, American History X is an amazing movie. It shows you how destructive Nazism really is.

How about Sin City? That has a lot of brutal, senseless violence. Much like NBK

Goodfellas is a good one, but that's from '92 I think.

The Hills Have Eyes is a pretty sick, and twisted movie. If you like Hostol ans the Saw movies, you'll like this one.

Fight Club
Kill Bill volumes
The Devils Rejects. :thumbsup:
Blow

That's all I can think of, but those are some of the movies in my collection.
