The question of naturalism is a fallacy, it does not exist... The photographic image replaces naturalistic experience.
Nature rarely does anything mathematically perfect, and naturalism results from imperfections and deviations.
I think I like about coming-of-age stories is that there's everything in them. It's a genre that kind of contains everything: you have the chronicle, you can go into naturalism, but it's also about transforming physically, so it's kind of a fantastical genre.
