The New 52, Corrected: Secret Six
What Happened: This is replacing Suicide Squad.
What I'd Change: Let's be serious, for a second. Secret Six sold decently and was a critical darling with an immense, hugely devoted fanbase. I'm not one of them, but I do know you don't let go of something awesome to put out something that sells about the same but is "just another comic". Bring Gail back, give her another artist (Nicola Scott's on Earth 2, which I like more so sorry Six fans.) and let her work her magic.
Why: DC needs the goodwill, to be honest.
