Sweet mother of Mew, there was a lot going on in this episode!
Honestly, it felt cramped—the writers tried to cram too much into 20 minutes, when they could have used two episodes for this—but I still enjoyed it nonetheless. The highlight for me was seeing Misty and Brock again, especially Misty. I wasn't expecting to see many of Ash's older Pokémon, but I thought we would at least see Charizard, given its iconic status. (The writers missed a golden opportunity for Kiawe's Charizard to meet Ash's Charizard.
)
I'm probably in the minority here, but I don't really mind that Misty and Brock weren't the center of focus for the entire episode. Instead, they were integrated into the group, while the Alola gang each had his/her own spotlight moment interacting with Kanto Pokémon. I loved the scene of Kiawe riding on Rapidash's back (he looked like he had died and gone to heaven!
). Shiron interacting with Kanto Ninetails was adorable, but not as adorable as Popplio and Dewgong playing with Popplio's bubble. I would liked to have seen a bit more of Ash interacting with Misty and Brock alone; but given how much else was crammed into this episode, I'm not really all that surprised that the Ash/Misty/Brock scenes were so brief. At least I got the Misty/Lana interaction moment I wanted, even if it was brief.
Team Rocket reciting their old motto was a nice surprise, but otherwise, their appearance was just a rehash of their standard routine. The best part of that entire scene was Bewear swooping down from a plane, scooping up its TRio toys, and then taking off with the rocket launcher from the remains of the Meowth mech. (I loved Misty's reaction: "What is this feeling?")
And then there was that blasted Jigglypuff. I wasn't too fond of that gag 20 years old, and I'm still not too fond of it. However, I did like that, while Lana, Lillie, and Mallow were gushing over how cute it is, Ash, Misty, and Brock immediately recognized that Jigglypuff and panicked.
I got a chuckle out of how Ash was the only one
not initially excited to be going to Kanto. Kid, you're not interested in going back home?
I suppose an extracurricular class in his home region wouldn't be that exciting, since he has already explored Kanto twice.
