"I know, I'm sorry, I can hear the rage and fury it might cause some fans, but if I'm absolutely honest, distance has given me perspective on that,” she said.
Actually, I think this is pretty awesome. Rowling is still thinking about her stories and her characters and able to revisit her writing decisions with a critical eye years after the fact. I've talked a little bit about how some of the things I've done in my stories I might have done differently if I had them to do over again, and it's great that someone as notable as Rowling can say "Yeah, in retrospect maybe I should have written that differently." Especially knowing, as I'm sure she does, that Ron/Hermione/Harry shipping was one of the most controversial and hugely absorbing issues in the fandom for many years and that saying this now will probably create more reaction than when she announced Dumbledore was gay.
I expect some people will accuse her of just trying to get attention again now that HP is fading from memory, which is pretty much what they said when she dropped the infamous Dumbledore bombshell. I don't get these accusations. JK Rowling has never struck me as a woman who's desperately in need of being in the spotlight or who courts controversy for the sake of controversy. She sometimes makes bad decisions and she admits it, but she seems quite down to earth and I think she just says whatever comes to her mind, even if it causes an uproar among her fans.
Anyway, this should be amusing to watch in those corners of the fandom still deeply invested in shipping and JK Rowling's after-the-fact pronouncements. Break out the popcorn!
