I don't have all that much to say. I didn't expect much of a story considering it was never Kubo's strong suit in Bleach. However, it seems either Kubo himself was trying to overcompensate for that in this project, or there was no direction in the studio's adaptation (I have not read the source material mind you)
Kubo's art and the animation steals the show, no question about it. There are some fun moments here and there, hell I caught myself chuckling once or twice. And the world that is built doesn't seem too original, but distinct enough to intrigue me nonetheless. Otherwise there isn't much to say to praise it.
I hope that there is more to come as I do think that if there is more time for the story to come into its own, it can be something good. However for now I find this to be anime junk food. A quick watch that catches the eye, but nothing substantial for it to be remembered as it is.
