One would think that, by now, coming-of-age films would have become a genre that’s been done to death — a dead horse whipped over and over again until there’s nothing left but sinew and bone. It’s a subgenre that fits under every umbrella in film, whether the protagonists are the so-called Chosen One or just a teenager struggling to survive high school. Admittedly, there’s very little room to create something new in the confines of a story about growing up, given the century-plus history of cinema, and the fact that, to pull out the old English major joke, we’ve been telling the same seven stories over and over since the beginning of time.
