I very much do not like the sentiment that authors can't write about identities and perspectives that they do not personally share or have experience of- a writer who only writes about what they know and never tries to step out of that is not a brave or good writer in my eyes, so I do not want to disparage the book based on the fact it's about teenage girls and it's written by a man. I could guess Warner's intentions while reading this that he wanted to portray some fun, cheeky, mischievous teenage girls who are rowdy and make dirty jokes and are not the victim of the leery men around them. However, I would say that this is one of the cases where the movie is more enjoyable than the book as on paper I found it difficult to differentiate between most of the characters (especially with the lack of descriptions and punctuation), whereas on film the actresses were able to inject some life and individuality into them. A lot of critiques of this seem to be accusing the author of fetishizing teen girls, which there are arguments for and against. Yes, they do spend the majority of the book talking about sex and who they want to have sex with and how much they want to do it. I'm guessing the intention was to subvert the typical stereotypes of teenage boys being the ones who are sex-obsessed and girls are the clean virginal ones (eg American Pie). No, Warner does not delve into the nuances and blurry complications of young girls and their sexual desires and encounters. Dodgy stories about men impregnating underage girls are sprinkled in but mostly just as a part of their banal lives, maybe to demonstrate the grim things that happen to girls that are normalised? But it's not explored and I don't think it was the aim of the book.
