Given the clueless approach taken towards the creation of this line, I'm not surprised to see that it's been scrapped. The story at Comic Book Resources gives this line:
Multiple sources close to the situation agree...that this development should be seen as a depressing indication that a market for alternative young adult comics does not exist in the capacity to support an initiative of this kind, if at all.
I disagree. I think the audience is out there, clearly. Someone is buying the books that gave DC the confidence to go ahead with the Minx line. Let me toss out an idea that you may do what you will with.
My diligent internet research reveals that the best-selling manga title is a series called Chobits. The creative force behind it is a group of four creators that go by "Clamp." All four are women. Persepolis was created by Marjane Satrapi. In case you were unaware, she's also a woman.
So who are the creative forces behind the Minx books? Mostly men. There were some women involved, but by-and-large the Minx line was guys trying to write comics for teenage girls. In the case of Mike Carey, who does fantastic work with the X-titles over at Marvel, they're 50-year-old guys trying to write books for teenage girls.
So DC(and Marvel, if you're interested), if you want to attract this audience, start hiring the best female creators you can find. Let them do whatever they want to do. Put that product on the shelves of the local bookstores and promote it as its own thing. Not as a big company most known for supplying movie studios with material trying to imitate something...but as something that exists on its own. Let the dollars roll in. Thank me later.
*I wanted to talk about this earlier, but decided that it would be good to let this post hang out up top for a little bit longer.
