This episode was kind of... meh. I had high hopes when I saw Bulbasaur, and the 30 Tauros, but then none of the other old Pokémon showed up? And apparently there was a photograph cut from the dub? Why would they cut that? Ugh. At least there was a bit of continuity, like the Teddiursa carving on his dresser.
Also, the animation, while nice for some scenes, was pretty lazy during others. I especially liked seeing off-model Bulbasaur keep glancing at Alexa's camera and 1997 stock pose Misty fade away into the sky. Oh, and Oak getting poofy hair twice (from Boomburst??) Real classy.
Team Rocket were okay, I guess. They did show up at Oak's for no real reason, but hey! They actually got some goofy expressions later on! And Wobbuffet is back, so that's nice.
I would have liked to see Giovanni's face when he opened Team Rocket's Pokéballs and saw that they gave him a Woobat.
