This was a good episode too, and a decent conclusion to the 2 parter, though it definitely didn't hit the highs of last week's episode. Personally, I found the first half a little dull, and I still don't like the fact that there's no pmention of Zeraora's ability at all.
Guzzlord's screams were pretty intimidating last week, but I don't know if I got used to it, but in today's episode I found it pretty hillarious since it sounded like a man with the worst screaming impersonation of all time. Anyway, so the plan is to push that glutton into the Ultra Wormhole, and Ash and Dia actually almost did it, before Guzzlord recovered and handed their butts to them, before a moment of plot convenience from Tapu Koko, which helps to reactivate their Z Rings. As expected Ash and Dia manage to pull off a dual Gigavolt Havoc and push Guzzlord into another world. Also, Tapu Koko you're clearly strong enough to trap Guzzlord in that Electroweb, so why didn't you just help Dia much earlier in getting rid of Guzzlord? Just makes you seem like a lazy Guardian.
Overall I give this episode a 6.5/10. It was a decent episode and conclusion for this 2 parter, and I thought both the Pikachu vs Zeraora battles were decent. However, I didn't like the extremely convenient moment of Tapu Koko charging their Z Rings, and the whole premise of Tapu Koko transporting Ash via some inter dimensional traveling rather than simply a worm hole being responsible. Highlight of the episode to me was of course hearing Ash Greninja's theme. That turns almost any scenario epic.
