Short review:
-Shiro Sagisu is literally a god -> Bleach OST Incantation [Complete Suite]
-The animation was very good.
-The voice actors were as always good
-The story wasn't really that good. The other movies were definitely better in this regard.
-The characters didn't really feel like Bleach's typical cast
The best thing about the movie is definitely the music, but I mean, it's Shiro Sagisu! His music is always great! The plot was nothing special, and the villain was not that good either. Also, the cast didn't really feel like Bleach at all. But the animations were pretty good, so it's definitely not a total disaster. I can definitely understand why Kubo wanted to remove his name from the credits!
Rating:
I would say on a good day it's a 7-8
and on a bad day a 5-6
So it's a 6-7 for me
