It's what Shokoti has been saying in the comic thread. Which is fine in many cases. I would prefer them to have stuck with Zatanna's costume though even for that instead of what I guess to be the corset and leather pants version we see on the cover of Justice League Dark. Also part of the reason I was hoping they adjusted Martian Manhunter's costume.
I could also see a stronger leaning towards comics becoming more and more about the movies that are made.
