Is ok. Nothing groundbreaking, and I guess it gets a little meh and somewhat cringe-worthy at times (or maybe that's the dialogue). That being said, I really liked the pacing of this anime. I liked the whole trains thing, it was a huge plus to the world building, which was decent, actually.
I think the whole anime was boosted a whole lot by the art and sound effects, tbh, and they are why I've given it such a high score.

I legit fangirled over these aspects of the anime. Character designs are solid, and backgrounds are top notch quality. I literally paused at times just to stare at whatever backdrop was on at the time. Because the art is so beautiful, it adds to the picture of despair of the situation with the kabane. Or something like that.
The audio really contributes to the atmosphere of this anime. Personally, I didn't care for the OP but everything else is spot on, I actually cried at moments.

I really liked the whole cast, who have successfully wormed their ways into my heart. However, from an objective point of view, the characters too are just ok- a little flat, tbh. That isn't to say you won't love them; you totally might.
In the end, I really enjoyed this anime, and episode 12 made me cry. Putting that out there for no reason. It has its vaaarious ups and downs, but overall it's pretty good, and better than a lot of crap out there. So I'm hovering between a 7 and an 8 for its final score. Ding! 7.5!
