I love how fans comment on how a writers "don't get" characters. I understand it in certain circumstances, but yeah, it's old now. Characters are three dimensional. Just because you don't like their interpretation doesn't mean they "don't get" the character. They just see them differently than you do. Just like I see Batman or Superman different than you do probably. It's all about your personal connection to the character IMO and that dictates your perspective on that character.
I'll wait until I read his Wonder Woman before I claim he doesn't "get it." I haven't had much of a problem with how he's wrote her in other things, so we will see.
