These were some pretty decent episodes. I did like the sense of dread around Doc Ock's plan coming to fruition. I do think they telegraphed the body-switch a bit much, and admittedly, I liked how it was handled in the comic better. That said, I liked the use of the Living Brain here. Since it's a pretty obscure Spidey character, the twist that it hosts Otto's consciousness can actually catch non-comic reading people off-guard. The cliffhanger was also great, particularly the juxtaposition of Otto taking over as Spidey and Peter being trapped in the broken husk of the Living Brain.
The description for the preview clips in Marvel's YouTube channel teased that Jack O'Lantern would fight Spidey along Electro and Beetle, but only his canon showed up. Hmm, either the writers for that synopsis misinterpreted how much he'd be involved or maybe he was cut from the episode. Poor Tinkerer. Maybe he should do more behind-the-scenes commission work, instead of using other villains' gimmicks.
The only small disappointment I had was the lack of cameos in the prison. Admittedly, I like watching prison episodes of shows because of all the cameos you could cram in there. But hey, at least Spidey got to revisit Electro and Beetle. Miles's reaction to Anya as Spider-Girl was great.
