So I just gave this a watch, and my opinion is that it honestly really is kind of bad. I have actually read CITY and like the manga and this follows it slavishly, but the delivery is all wonky. The artwork is gorgeous but it's just so badly directed and dry. Like the manga is formatted in a very specific way to grab your attention and quickly deliver a dramatic punchline and this simply isn't here. It's just totally abysmal. A real shame.
The mangaka actually does animation and it's unironically better than this show.

Like this is really quirky and upbeat, the anime is just tonally dead by comparison.
Sorry but I'm out on this one.
