So, think the idea of the story is great but how it was handled was terrible. It felt a bit too silly and that is not a problem but feel like we needed to have the gritty stuff too. After a while it felts like this world could never work and one way it makes sense with god doing what he wants but that feels like no solid ground.
The end is just plain bad and if this was the plan from the start even with 10 volumes then that is just tragic. Like what changed? Like they got 1000 years and then what? Like god can just start over again or go to extremes or just kill all people for fun like he did in the last chapter with the angels.
In the end great idea but that is all.
