Earlier quoted context omitted.
The director said she did want to denounce over-sexualisation of young girls with this movie. I (and 2 of my friends, feminist women) think she managed to do it, with a relatively good and a relatively subtle movie. Talking about over-sexualisation of young girls require to show stuff linked to... over-sexualisation of young girls, to show some aspect of reality... But if you find this movie erotic, well the problem…
If you turn off the sound (mute the movie) does that message come across? Because there are people who will watch oversexualized stuff like this with the sound off for their own purposes. You don't have to do the thing you are being critical of in order to be critical of it. There is nothing sophisticated in "pushing boundaries" to make a point - it's sophistry to justify child pron, plain and simple.
Of course you don't have to show what you show, but then you make an entire different movie. The fact you could make a different movie, does not make a thing "morally" bad or wrong.
The public swimming-pool of you city is probably much more exciting for pedophile than this movie. Do you suggest swimming-pool are child porn ? Should we close it ?
