It's really hard to tell the difference between "intended to disgust the viewer" and "intended to tittilate the viewer with a fetish I don't share". I mean, any scene of sexualizing children is going to disgust me. How am I supposed to know which ones are meant that way?

(Also, consider the existence of exploitation films, which loudly proclaim how bad X is in order to have an excuse to show X to people who like seeing X.)
