Does this mean Waid's run on Hulk is over?
God I hope so. He's been responsible for some of the most boring Hulk 'stories' ever. I thought Aaron's wacky mad Banner stuff was a bit of a come down from the fascinating post-WWH intelligenCIA stuff, but this run has been hugely disappointing.
Oh and that feat, if I read it correctly, basically leaves "Hulk squared" in the past (and maybe thus, in the present) as a separate entity as well as returning Bruce Banner to "Savage Hulk" levels as he is Banner from the past.
So now we have SpikeyHulk who is also the proper 616 Banner, somewhere in the universe and we have origin-point Banner - uploaded with the digitised consciousness of 616 Banner - as the primary Hulk of 616 (a Savage Hulk, at that).
They really are determined to waste all the good character development that went on over the years from prior to and through Planet Hulk/WWH/WWHS/FOTH ...
Retcon punch was absurd and messily depicted. If (and given Savage Hulk has done similar before), he could punch through time to the present, just as long as he had some chronal material to hit, why was he not able to punch to the past?
