Isn’t this the continuation of the unadapted parts of the original manga? They had announced it earlier, I assume this is it.
Honestly, divided if I should watch it. I love episodes 1-63 of Bleach, honestly some of my personal favorite arcs in shonen, but I switched to the manga after that and the story slowly dipped in quality for me until it was just downright bad IMHO. I read up to the defeat of Aizen which is what the original anime ended on, but never read further. I had had enough.
I’ve heard some say the arcs after this are much better, but I dunno. Having said that, I do want to support the mangaka Tite Kubo as he got death threats and such from people who freaked out over where the manga went (fucking Christ, does every fandom have to have these jackasses? You didn’t like a thing, move on with your life), and I feel bad for the guy. I did buy his mini-series spinoff manga Burn the Witch as that recently got a physical release in the US, just need to read it sometime. So I might watch a few episodes purely to show support, and hey if I’m liking what I see, I‘ll stick around.
