We went to WonderCon this weekend and the buzz around the new Batgirl Beyond storyarc was most gratifying. I don't think I was on the floor even two hours, yet at least a dozen people came up to me, excited about a new Batgirl.
The internet's had a fair amount to say about it as well and, again, the response has been quite positive indeed.
As the brilliant Annie Wu mentioned, she put a ton of thought into presenting a Batgirl she'd have liked to have seen when she was a kid, and I think it does come through in every panel. And I look forward to being able to share her character designs and other cover sketches—there's no such thing as too much Annie. Or, apparently, Batgirl.
