Kaguya's final moments were distasteful due to:
1) Sakura being there
2) Kakashi being there
3) Kakashi having FULL god chakra flowing in his veins is neg diff
4) Kakashi being far more experienced and older played a bitch role
5) Kaguya was too motherly and never really did want to harm her "children" despite of raving about destroying them
6) Why and how was Sakura even there?
7) Tenseigan and Rinnegan weren't used
8) BZ could've done more
9) Her appearance acted more like a highlight reel of her abilities which might I add only showcased Part 1 abilities.
I mean the only thing that was different was her dimension travels and the last TSO tech which never came into fruition. Otherwise, all her tech have been just Part 1 techs on major steroids.
