I don't get the criticism of TYBW other than the ending lol. It has so many great fights , bankais and abilities. Bleach was always about fights for most part.
There is a sublte depth to bleach's themes which kubo excels at.
i feel like anything that has to deal with the soul king and lore about those things. Yhwach of course was interesting and very cool and surpringly a very scathing critic of the Abrahamic god
That is fair, Even I myself was expecting Kubo to show the full 1000 year flashback to the quincy war with the original gotei 13 and the soul king etc. That being said "Can't fear your own world" does a great job of tying up ALOT of lose ends from TYBW and even gives us some great info on the soul king.
Yhwach is a great final villian and even though as a character I love Aizen more, I can't deny that as a pure "Villain" Yhwach is better because he accomplishes so much more in what little time he has. My one gripe with Yhwach is that after he absorbed the soul king his character went off the rials and became VERY generic. Also I felt Kubo went to far with his powers etc. But that is my only complaints with him. Pre-Almighty Yhwach>>Almighty Yhwach in terms of character.
