Simonson's art seems a little more rushed in this run, and I think he may have been struggling with the deadlines, judging from the odd guest inker and, in the case of the last issue, guest penciller.
But his writing remains on point. And he's got a lot of stuff going on here. Simonson doesn't write a simple one and done issue, or even a two or three issue arc. He writes epics that span multiple issues, while also setting up what's to come after this epic ends.
Honestly, his storytelling is so refreshing, both from a character standpoint, as well as from his avoidance of the "villain of the issue" plotlines. He sees that the pantheon of characters in this series is a rich vein to be mined. Sif, in particular went from "But Thor! You must let me come on the adventure! I'm a warrior too, remember?" to "Screw you. I'll do my own thing, and show you all what a real warrior looks like."
But he's reinventing all the characters. There's noticeable changes to Odin, to Loki, to Balder, to Volstagg, to Sif, and...yes, to Thor himself.
I only hope the quality of the writing continues.
