On topic... I haven't see it and won't... But people have said Cuties is pretty much all about saying "this shit is fucked up". And the general response to Cuties has been "what the fuck is this?" As in, if its some insidious plan to get people to accept p***philia, it sort of failed.
p***philia will never be accepted, since in order to get it accepted... Well, you're going to have to roll back changes to people's views on consent. (Children can't consent, period.)
I can't speak for Cuties, since I'm not going to watch it, but it is possible for a piece of media to show something without glamorizing it. If you're making a movie that wants to show war as a horrific thing, you're not exactly going to want it to be bloodless and family friendly. On issues with sexualization, it's harder, since humans are weird when it comes to this... What disgusts someone could turn on someone else... But it's possible. Just hard.
