He cast Gadot and helped produce WW. For her lack of presence in BvS she was one of the more memorable aspects, aka one of the things he did positively.
Or are you just going to shit on him just because?
A) There are thousand of actresses out there who can play Wonder Woman. It's not like he scorched the earth looking for the one and only woman in earth able to play WW.
B) If he didn't help producing WW's movie someone else would. They were going to inevitably have WW anyways for Justice League.
C) Her lack of presence in BvS is on Snyder's part, if anything.
I'm not shitting on him, just pointing out how the people deserving of the praise are the director and the cast, not Snyder of all things.
