I'm with Punchy (
), as someone who does not like the Eternals and thinks it's Kirby's weakest Marvel work, I like the fact that the Celestials are being brought down a bit here. It shows that they aren't the super-powerful cosmic force that they've been made out to be. I really like that as a pairing with the whole idea of the builders in Hickman's Avengers. It shows that there are all kinds of things going on in the MU and that one supreme entity doesn't trump all others.
I also like the fact that with Odin's enchantment, it gives the Asgardians an edge in terms of god-stuff. With all of that, it really increases Thor's personal stake in the series and also ties to Thor: God of Thunder and promotes that "shared universe".
As much as I think a throw-down between Jarnbjorn and Mjolnir is cliche, I'd love to see it go down.
