D-E-A-D. It's not that great of an arc. The Asgardians were killed, Thor had to have his quotable quotes...and lose. Thor is now their "Valhalla"...meh. Essentially, Ultimate Asgard has already experienced ultimate Ragnarok, thanks to Reed Richards. Lame.
I think the battle between the asgardians and the ultimate "future foundation" went too quickly for my taste...would've preferred the asgardians mauling more enemies first before being overwhelmed. However, considering the overall story, it's just about to begin act 3. imho, a little bit premature to judge.
