Zack Snyder has always been a talented director (witness the first ten minutes of the Dawn of the Dead remake), he just got caught in the web of over-the-top style in place of substance. Hopefully he Sucker Punched it all out of his system. I pretty much felt like never watching another movie directed by him again after that.
I'm cautiously optimistic about this. I'm a little worried about the movie feeling too portentous for what it really is, but I like the general approach and what seems like a more naturalistic tone (if you took away that weight-of-the-world soundtrack).
