Query: Raw, vicious, challenging, and VERY underrated

It is not surprising to me that the critics couldn't handle this movie. This movie wears no gloves. This movies is only for the hard core, for those who don't shy away from the dirty truth. I must admit, this film isn't an easy watch. It isn't a movie you put on in the back ground during a fondue party. You don't put it on low in your kid's room after you put them to bed for the night. This isn't that type of movie. This movie challenges you, like a good book would, it leaves a scar, a lasting impression. So if you want to watch a great film and you're not a pansy, you should see this one, as soon as possible!
