Here's my review:
Thought it was great, really did.
While it did read pretty fast I was alright with that as both Secret Invasion and Dark Reign were drawn out. So this pace was more than welcome! Siege being only four issues will most likely be like this, with the rest of the story being told in the tie-ins. To me this only means the tie-ins will be that much better (hopefully).
Gotta love Ares. Did you read his DR mini by Kieron Gillen? If so, you know where I am coming from. Here Bendis continued what I felt Gillen gave us - an Ares we can like! He felt like Maximus from Gladiator to me when rallying the troops! Heck, he more than likely mentored Maximus as Ares is the god of war!
I dug the Sentry stuff as well. We all knew he was the one who could "take on the immortals" when Baldur was speaking to Loki. Still, turning the page and seeing Bob busting through Asgard itself was awesomeness! Then he saves Norman's hide and takes on Thor!
Speaking of the thunder god, guess we know why JMS bid Marvel goodbye, lol. He got HAMMERED! Or so it looks. Add to this the ending with Steve Rogers and the inclusion of Fraction's Invincible Iron Man Stark:Disassembled arc (which has been very good, imo) and we get a hint of the return of Avengers Assemble!
I thought the art was great as well, particularly in the above mentioned pages with Loki and Baldur. Loki looked bad-arse!
Things seem to be moving quick with the Siege of Asgard and I think readers will be rewarded when all is said and done - or destroyed!
