Seems like it's meant to be deep and thought provoking, but in my opinion it's a very basic storyline with little development. Nothing that happened in the book is explained or explicable (I don't think this makes it "mysterious" as some others mentioned, there just doesn't seem to be enough substance to make it worth dissecting). Some also commented that it well describes adolescent life... It really is not as most of main plotline involves actions that don't make sense and are unlikely to happen in real life.
