The art style is the one thing that stayed pretty consistently great. Manga readers may crow a bit about an animated show not having as much detail as a static manga, but they're every bit as wrong and irrelevant as every manga reader is. For some reason I really love that particular shade of orange in Emma's hair, and the purple in Mama's eyes. The real star of the show, though, is the character designs on the adult characters. They seem normal in screenshots, but in motion their hulking size relative to the main characters and powerful presence really solidifies one of the best aspects of this show, which is nailing how overwhelmingly powerful adults feel as a kid.
The story is one of those annoying things that's hard to talk about because of spoilers. It's decent. Some parts can get pretty predictable but it has some solid curveballs I didn't see coming. Incidentally, this show has one of the best "shit hits the fan" episodes I've ever seen, and a solid entrant in the "shit hits the road" episode contest as well. The moments where it feels like everything is crashing down around you are when Promised Neverland is at its best.
When it's not doing that, well, it never quite gets boring but you can feel the stretch as it attempts to cover the distance to the end of the episode. It can do tension well, it can do revelation well, but it's not quite as good at being quiet. You'd probably be looking at a very different score if it could.
I'm ultimately glad I picked up Promised Neverland. At its worst, I was mildly disappointed. At its best, I was on the edge of my seat.
