Well that's entirely put me off.
Not because of her bigoted rants. I would imagine that isn't going to show up in the show all that much -- I can't imagine how she can work it in without making it overly obvious.
No -- my problem is that Secrets of Dumbledore was crap. I mean REALLY bad. So if she brings her "special touch" to the series the way she did with that then god its going to be appalling.
