If you want a deep review, look at the other reviews. If you want a short one, here:
This anime starts off very slowly and can get boring at points, BUT, it's still amazing.
The story might seem simple, but tbh this thing goes deeper than the lore for The Matrix
If you like action, isekai, and slice of life, you'll like this.
*note: the humans are made to be boring, don't worry about it.
