My point isn't, "Eww, they're sexualizing a teenage girl," so much as, "Yet again, one of the Big Two self-sabotages an excellent opportunity to expand their market, doubtless while whining about how they can't get readers outside of a certain demographic."
I mean, it's a comic about a teenage girl from another world trying to find acceptance as a superhero in ours, which is a perfect, "Look, kids, it's sort of like magical girls, only it's superheroes, and with, uh, forty years of continuity..." opportunity if I ever heard one. And it's written by Sean McKeever, who wrote Spider-Man Loves Mary Jane, which IIRC was quite successful in bookstores. Since manga fans follow creators around rather than characters, McKeever's work could be a potential hook for getting some of those SMLMJ readers to follow Marvel more closely - certainly worth a try.
Instead, butt shots. And then Marvel and DC continue to wring their hands over their aging, heavily-male reader base and wonder just how they can break into the manga market.
