If he cared more about Jon than Clark he’d probably be sticking with Jon in Superman rather than Clark in Action. Still I’m waiting to see how his Worlds of War FS one shot does before leaping to conclusions. That doesn’t have Jon in it at all and is 100% focused on Clark. We’ll see how well he writes Clark soon enough.
He’s said Morrison & Waid are his favorite Superman writers and he liked Superman #400, so I don’t want to accuse him of not really liking Clark just because he likes to talk about Batman stories lol. Someone should ask him what his top 10 favorite Superman stories are though, that would be useful info to know what kind of stories he likes to read, because he’ll probably try to write similar ones.
