An absolute love letter to the cheesiest corniest most beloved beautiful story telling tropes and beats in all of anime. One of the best anime original anime I've ever seen and one of the best anime I've seen in a good while. Solid 9/10. It would have been a 10/10 Masterpiece it played the story too safe. It was predictable a lot of the time and very by the book. You could follow the three arc structure it had going episode by episode which while could be intentional seeing how the show was based on a movie within the story. If that was the case then bravo for such meta storytelling. An absolute love letter to the cheesiest corniest most beloved beautiful story telling tropes and beats in all of anime.
The characters were phenomenal. Some more than others. Memmeln felt very under utilized despite having her own personal tragedy and character growth but it was so short and felt like too easy of a change for someone with such deep seated anxiety and issues. The Bird Director was probably the biggest disappointment. She was neither an ally or an enemy. Just a random inclusion despite being such a significant figure when it came to "A Tale of Perishing". Her inclusion had a lot of potential as an antagonist but it never went anywhere and frankly if was removed all together nothing would change. Luke, Unio, Justice, and of course our heroine Natsuko win the gold star for not only being just great characters but each having their own well rounded character arcs and development. This show was not carried by the plot or the references to other anime, but these characters.
Shifting to the plot, it was very by the book. A character like Natsuko struggling with pressure that came with success and her own shortcomings sent to a world where she is given god like powers and omnipotence as she struggles to use said powers and knowledge to change a fate written in stone. She did everything she was supposed to do for a character. She struggled, grew, evolved, and in the end over came her short comings established in the first episodes. It was well executed, handled, and animated with incredible skill and grace. It was also safe. Nothing really stood out about her character or the story as a whole. The anime reference and easter eggs were a nice touch for any anime fans but overall the plot was standard, safe, and predictable. Everything from beginning to the last scene was exactly what one would expect from a series like this. It was amazing, beautiful, and exciting to watch as well.
In a lot of ways, Zenshu's predictability is part of its charm. It truly is a love letter to the 3 arc structure of story telling and all those movies, shows, and stories that follow it. It was not trying to rewrite the rules because it was celebrating them. This series is a celebration of anime and animation.
