Well, for starters the animation on this show is absolulty beautiful, I mean the details on certain character and the way they gave creatures and such texture BRILLIANT! Second, the script, depth and character grow certain character get are so well done that even a show made for kids can reach a much older audience because of the cleverness of the show and the way they wormed certain uncertaintes some adults get, into the story is a job well done by the writers. Its just amazing! So give it a go. And it helps that the 2 shows before this: Trollhunters and 3Below were'nt half bad as well. And third, the cast is full of a-lister and the only way you'll figure that out is if you google the cast! Amazing!!!
