I'm a well read grad student who's bluntly honest about all things, although I try to be most honest about myself.
I may be wrong, but I believe this may be the first appearance of Riri Williams. That being said, I felt she wasn't hyper sexualized - one of the controversies, at least one other being a 15 year old black girl took the name Ironheart, which is already a name for a porn parody Iron Man :/
I really enjoyed her, and felt that she was true to the later issues I read with her in them, so that continuity was nice. (I think those were written by Bendis, too, though so no real surprise on the continuity in characterization there.)
There was more tangible Civil War II issues here, as Iron Man is in the middle of it all, and being attacked by the Inhumans for his part in everything. And while Riri becomes part of everything through this, a lot of time is spent talking about Civil War II related things.
It didn't feel like a Civil War II book, though. It felt more like a tangential to that, and Riri helped with that feeling. Loved!
