As someone who fancies female characters being written as more than a love interest or someone to be raped, and don't believe sexual ambiguity makes a villain more frightening, I'm on board with what she's writing.
But it’s an important character to many people, and I think the visceral reaction to this kind of criticism is because these critics have a ton of political power in certain settings and tend to trigger reactions that go over the top.
No political axe to grind about Batman or Miller, it’s just not a character or style that I personally care for. My wife loves Tim Burton stuff, I do not. I love old school Star Trek, she would rather watch the weather channel lol.
that said I too hate that non protagonist women are mostly treated as props to a story and protagonist women mostly embody male tropes in a woman body - I think there can be much more than that.
albeit there's some interesting takes if you search around, like in the amazon "invincible" - but I guess a miniseries has more space for it, and it's for a more adult audience to begin with.
Perhaps publishers are misallocating the pie.
This is an open secret in the comics world, the “comic book industry” dedicated largely to superheros is only a tiny fragment of the comics sold now. Imported manga started eating their lunch years ago, too.
