Let's put it in perspective...it's a child simulating sex to an adult population. I'm not trying to act all high and mighty here, but everyone should see something wrong with that - **** artistic merit or whatever those artsy bums call it.
I wouldn't say it's simulating sex...that implies some sort of desired titillation for the audience. It's simulating RAPE. It isn't supposed to be titillating in any sense. It's very disturbing which is the entire point of the scene.
