I agree, in many places it's quite cliched. Worse, though, is that in some it's just a bit bland. 'frizzy bouncy hair' is a surprisingly boring way of describing something, and it's a very unwieldy phrase to have in a song, it's trying to use a book's way of describing something in a song's story and it plain doesn't work. There's a few bits like that in this song but that's the most prominent.
