Yeah I know, but one can always dream.
I do think they probably overreacted though. WW was going to be a hard sell no matter HOW good the movie was (and I think it's one of their best, personally).
Preaching to the choir. The Green Lantern sequel was also messed up because of the edict, as was the Teen Titans project.
Most of the public just doesn't find her to be all that cool or interesting. Other, younger female characters like Supergirl or Batgirl would probably do a lot better.
Based on how the books go, maybe or maybe not. WB's conclusion was that female-lead projects don't "sell", which is why they selected S/B: Apocalypse as their "Supergirl" inaugural project.
