I started reading this series before I read Planet Hulk (still got WWH to catch up on) so now I'm puzzled why Hulk's back to Dumb... on comic sites most people seem to be ripping Loeb a new one over it, and especially over the lies told about finding out Red Hulk's identity in #6.
But with 7, I didn't mind Joe Fixit returning. I'm not all that up on Hulk's history, but I bought that the Joe aspect of Banner's psyche could pop out because it was Vegas, night, and stuff was happening. It might even be nice to see similar stuff happen more often, where a 'different' Hulk appears depending on the situation. Not sure if they've ever done that, but it wouldn't surprise me.
I got it mostly for the Adams art, and it was fun but brief. Moon Knight going apeshit on Fixit was a bit odd.. did he miss the gaunt, furry monsters that Fixit was throwing around? The Cho part was ok. It was just a silly story and yet another excuse for Cho to draw boobs in action. We learned zip about Rulk, and that probably won't change anytime soon.
