Animation & Art 10/10 - You can tell the love and effort that was put into this arc.
Story 10/10 - Bleach has been known for all action and no story, but we got so much revelations, news, lore, flashbacks, and so much more with this arc only.
Pacing 10/10 - The problem with OG Bleach was the pacing which is bound to happen with the anime being so close to the source content, but the pacing in tybw was perfect. not too slow but not too fast.
Conclusion: I came into tybw not expecting much, but this series blew me! The best return of any anime i've ever seen. I can't wait for the 2nd cour to come this summer. ICHIGOAT!~
