It's a shame that they bungled Ultimate X-Men as badly as they did, but that's mostly down to the wrong writers. The whole Ultimate Colossus thing could've been a watershed moment if a decent writer had followed Vaughan. Roberto Aguirre-Sarcasa would've been pretty awesome.
Wasn't Minx a DC line of comics aimed at girls? I didn't think Divas was a good idea, no, especially with the covers they put on it. I don't blame them for the basic idea, but the marketing is bungled pretty hard, the same way they fucked up the old Emma Frost book with the Greg Horn cheesecake covers.
It's kind of a two steps forward, one step back thing, really. On the one hand, they're bringing back just about every character they've ever used and are getting tons of mileage out of the back catalogue, while they're paying a lot of really good independent artists and writers to do quick fun superhero stuff.
They're also working on their racial balance fairly well, with Luke Cage hitting the A-list, Amadeus Cho, Jimmy Woo, Greg Pak's War Machine, the inexplicable decision to make the post-Ellis American Eagle a total badass (the dude used to look ridiculous), more women on the Avengers even if they did kill Jan, and a higher-profile role for Black Panther.
On the other hand, yeah, their attempts to market things specifically to women have largely been embarrassing to watch, I really wish they'd put long pants on Carol Danvers, and I can't stand to read Amazing Spider-Man at the moment.
