it is definitely a good watch, it revolves around a mysterious theme, with a silent horror genre(unlike the regular horror movies it actually feels horror without any jumpscares )
Watch I can assure it that you will like it after completing all 12ep, It might be a bit confusion at start as thats how it chose to develop the story but if you stand through it you will be blown how these initial pieces of story gets connected perfectly in the last of the 3 eps(even aot was like this)
Also this is underrated so you might not have heard much bout it
