I had missed the Fantastic Beasts kerfluffle, and I have to say her current bout of idiocy is far more than disappointing.

I have a really vague recollection of someone somewhat salty — I think it was Stephen King but were I to — in the middle of a generally quite positive review of one of her Harry Potter books suggest that there was a certain point where too much success became dangerous. I meant it in the context that no one dared to edit her work properly and so obvious issues were not corrected when they ought to be, but one might find other applications for that comment.
