Well, at least she was rebelling with fashion instead of other things, which I'm grateful for. Lots of other young starlets can learn from her.
But I do have to ask, what does putting on nail varnish have to do with Hermione? Why wouldn't she be allowed for to do that?
I love that the directors kept saying, "She's too pretty." If Emma thought she looked ugly, even as Hermione, she's quite wrong. There was no need to rebel there.
