Very, very good. Lots of lore, great and detailed character design, and the animation is lovely and smooth. Great for those who want a series that they can get invested in instead of just being short-term entertainment. Some of the parts in the end episode are a bit cheesy, and there could be a bit less slo-mo, but overall, it doesn't take away from the rest of the episode or series. Some people fuss about the biblical and adult themes, but I don't find them disturbing or distracting. I find it fitting, considering the setting of the show. Others fuss about the color palette or character designs, but I find them wonderfully detailed and unique and think that the similar color palettes and designs fit the fact that no one wants to stand out, as it leads to them being targeted. I also believe that, despite the similarities, each character is still different enough to be distinguishable. In my opinion, those who complain are simply not willing to put forth any brainpower into understanding the show. 10/10 would watch it again.
