I understand if some (especially men or boys) are not into this or do not think this has a purpose or whatever. If possible you have to keep in mind who the target audience is for the movie. Obviously in this case it is female and it is teenagers. While the actors are above that age (they play or pretend to be), they are doing a really good job.
Movie tried to give a voice to those who were not represented in movies that much. And it did a good job at it. Of course it hit almost every cliche hole on its way, but it is a fair price to pay for an overall still funny movie. And as you'd expect with a European (German) movie, nudity is not frowned upon or seen as something evil - hopefully you won't be bothered by it either (it is sparsely used anyway)
