... don't be one of them. It really is despicable, dehumanizing and just plain wrong. Now even if you like "torture porn" movies, I would find it hard to believe you could find any redeeming factor in this. Yes there is the ending, that gets a bit artsy, but this is a clear case of too little too late.
This was part of a "limited Edition" double DVD Grindhouse collection. This was worse than the other movie which at least tried and sometimes succeeded to be funny and entertaining. If you've never heard of this, good for you. I hope I'm not the reason you came here, but if do yourself a favor and don't watch it. But if you do, skip to the last 10 minutes or so. You don't have to have seen the rest to have an understanding of what is going on or have redemption (if that is possible)
