Fair points there, though I have somewhat more faith that those will be answered and explored as this series continues. With how successful it's been thus far in winning over critics and fans alike, that's almost a fait accompli.
Yeah, Hickman would be perfect for a more explicitly cyberpunk-style story where the world is secretly (or openly) divvied up between megacorps that have turned entire nations into their personal fiefdoms, since that's not very far off from the status quo he's established in this new Ultimate Universe.
