I wouldn't wish this on my worst enemy. I don't know if it's more disturbing to think about the person who wrote this or the person who wrote Saw III. This seems to highlight worse facets of human existence and I fear the mind that thought he was creating something that children should be exposed to.
I'd like to think that they were all sitting in the green room a few minutes before this, taking long drags on their cigarettes. They take care not to look one another in the eye. They all know their work is shameful, but it keeps a roof over their heads. Finally the little girl rasps, "Let's shit this one out and go home."
