I personally think this was the best update so far. I can understand some people not liking X or Y, but to me, it was exceptional. The only negative I found was that the pacing was a bit off with Kira, but it was needed if they were going to be apart. It's not like I didn't enjoy all the scenes with her; I like her character.
As for the positives, I appreciated all layers of the story being shown throughout this update. The pig quest was fun, Luna's struggles were interesting and probably important for us to know, and the conclusion of the chalice quest was pretty good.
Edit: The ninja girl backstory was good too, almost forgot.
Also, I don't have a problem with Pearl's actions. It was a bit forced to push for the final combat, but it didn't upset me.
As for Eliza accepting everything so quickly, I would do the same if it were a choice between never walking again and being a burden to everyone around me, or turning into a monster and trying to control that monster. It'll probably bring a bit of drama, but hopefully, everything will work out in the end.
