Beyond the fact that I think Rowling understands that, that was not my point.
Rowlings and other artists should be allowed to create as they please...
I'm pretty sure she did.
My point was, and continues to be, that Rowling knows her fan base. I don't think a healthy understanding of that harmed the books in any way.
Unfortunately, I do think that Rowlings (or more likely her publishers) were servicing her base... Tweens and Teens. But I think that most of Rowlings eleven - sixteen year old fanbase could have survived a darker ending. It’s a pity that instead of exposing these teens to a darker ending and thereby getting them excited about classic literature, Rowlings decided to pander to them and make her ending.. like Disney teen.
