I was pre-desposed to dislike this episode, as the premise sounded horrible, and that they were going to re-tread the "Freaky" episode, but I was pleasantly surprised. While it was nowhere near as good as last week's Iron Fist-centric episode, the episode was pleasant enough, with the humor being amusing rather than idiotic (even the chibi moment). Granted, Spider-Man in the Hulk's body would have been easy to resolve without the Thing, as all he would have had to do was surrender to Coulson, then SHIELD would have easily captured Hulk-Parker. Then they could have focused on Mesmero (and yes, it would have been easy to write, with Mesmero body-swapping SHIELD agents and civilians as distractions to escape, but I digress).
Some of the jokes were tedious "Purpling my pants" - but other scenes, like Stan Lee's literal soapbox, was mildly entertaining.
The most interesting part was the quest of SHIELD and the Hulk to transition Hulk to a smarter intellect, in prep or the smarter Hulk in AGENTS OF SMASH. Interesting way of trying to dovetail the two series (and possibly three, as different versions of the Hulk was a major stumbling spot for continuity).
