Post-Flashpoint, Wonder Woman has been written by Justice League scribe Geoff Johns and Wonder Woman scribe Brian Azzarello. And the differences between their writing shows. Geoff Johns has been building on the pulp elements of Wonder Woman while Brian Azzarello has been building on her mythological side. And there's hardly any overlap between the two writers. I believe I know why.
Johns is the Chief Creative Officer for DC Comics, so he probably wanted to establish some elements of her mythos himself (her origin, Steve Trevor, her personality, her traditional villains). Brian Azzarello is probably not allowed to use these elements until Geoff is done. He may also not want to have anything to do with what Geoff is doing. It's clear that Azzarello wants to tell timeless Wonder Woman stories, so it would make sense for him to avoid the "Electric Blue Superman" elements found in comics today (such as WW's relationship with Superman that is sure to end post-Twilight of the Superheroes crossover). Some key ways Azzarello has differed from or ignored Johns include:
1) Giving Wonder Woman a different personality from Justice League
2) Ignoring the Wonder Woman status quo and plot threads
3) Avoiding the pulp elements of Wonder Woman for the Olympians
Again, I think Azzarello's motivation for not interacting with the rest of the DC Universe is that he wants to tell timeless Wonder Woman stories that are not bogged down by elements of the New52 that may be dropped later on. And Johns can't really do anything about it because he's still not done establishing Wonder Woman, Azzarello's Wonder Woman is selling better than before Flashpoint, and Johns doesn't have the time to write Wonder Woman's solo himself.
I'd love to hear your thoughts on these writers and my theories below!
P.S. I'm loving what both writers are doing for Wonder Woman
