The Legend of Korra shares the same expansive world as ATLA, but many years in the future. The visuals are amazing, possibly even better than ATLA. It’s story its story is lacking since each season has a “villain of the week” vibe, and the series lacks the whimsical filler of ATLA.

They are both animated by Studio Mir, so they both have the same amazing visual appeal. Kipo also has a similar world, with lots of crazy animals. The plot is less grandiose, but still very fun. Also they both have female protagonists.

Kipo has a great soundtrack similar to Into the Spiderverse. The same person is behind both of the soundtracks. They both also have great animated visuals.
