It probably doesn't work outside it's Mexican Spanish audio, but it wasn't as bad as I was expecting. I'm old enough to remember the original Flash Poeta Huevos Huevo Cartoons.
Some people aren't realizing that Nezha Reborn (2021) has nothing to do with Ne Zha (2019), despite featuring the same mythical character, it's two different studios. This Light Chaser Animation Studios production seems to be a God Universe tie-in with their previous release of White Snake (2019) and their upcoming White Snake sequel.
Though White Snake is a much more solid picture, I enjoyed the last 30min in Nezha Reborn.
For the sequel of the other Ne Zha, look for Jiang Ziya (Legend of Deification).
