I've always thought that people made too much of an issue of that. I can't recall a single time that one writer denigrated the writer of the series they just picked up. And Thor, while he has had some harsh moments, has been compassionate, regal and controlled.
He could not be more different from Aaron's Thor.
And while yeah, I'm getting tired of hammer issues, Cates has made it pretty clear that there is something wrong with THE HAMMER, and not Thor. He's had Loki lift it twice now, I don't know how he could be any more clearer
