Kipo and the Age of Wonderbeasts is easily the best children's cartoon I've ever watched. It's concise at 10 episodes per season and 2 seasons currently out, but the show just came out January this year and has already had a second season, so I'm sure there'll be more soon.
I really think it beats out every other fantasy adventure cartoon I've ever seen. The soundtrack is fantastic, the artstyle is transcendent and uses both 2d and 3d animation really effectively, the characters are multidimensional (also there's really great black and queer representation and they don't treat it like a big deal), and the world is...oh my god, the world.
I watched one four minute clip and it compelled me to watch the first episode. I binged the entire first season in a day. I'll nsfw it for extremely minor spoilers (the segment in the clip is at around episode 3), but if you like any modern fantasy adventure cartoons, you would be remiss not to watch this.
