What's just wrong? Child rape or movies about unpleasant subjects? I agree with the former but not the latter.
I'm really trying to think about art here. What's it for? I can understand a novel about a rape of a pre-pubescent or just scarcely pubescent girl, I'm wondering about a movie. And it depends on what scenes are filemd and shown. I can barely imagine an artful portrayal of a rape, but it's hard for me to imagine that I would be in anyway edified by an "artful" portrayal of the rape of a child. And it sounds like that's what they're offering here.
