What's wrong with Luna, you ask? Honestly, nothing yet. Except that the actress they picked to play the role doesn't, in my opinion, look like the Luna in the books ( I mean JK's written description, and my mind's interpretation of that). If I took her appearance as an indication to how she will act her part, I for one will be disappointed. Of course, she could be very well suited to the part and play it well enough to earn an award, that remains to be seen. All in all, I think only a small handful of actors have done their characters justice. Worse still, because so many of the actors are children (or at least not fully grown), I feel they're maturing in ways that aren't befitting to the book characters.
