Seriously, if there is anyone who should be barred from the set, it should be Zack Snyder, a man whose overwhelmingly gray, depressing tone is going to turn me off of seeing DC heroes on the big screen. I have voiced my opinions on Man of Steel (and how much I don't like it) ad nauseum here. But one thing that deserves rementioning is that Supergirl was rumored to be in the second film. After seeing the first one, I am thrilled that Snyder isn't going to be able to put his thumbprint on the character.
Imagine that ... me, as a Supergirl fan, glad that she isn't in a mega-blockbuster movie!
Now it sounds like this was just a visit and he isn't going to impact the approach of the show. I mean it Berlanti Productions, don't let the siren song of 'gritty realism' deter you from your course. You'll end up dashed on the rocks!
My guess is Zack Snyder's mental picture of Supergirl is something like this ... without all the context of course.
I DON'T WANT ZACK SNYDER ANYWHERE NEAR THIS SHOW!!!
