For those who've long waited patiently to see one of China's greatest animated features, it is now finally online with English subtitles on Crunchy Roll. I'll wait until later for a larger write up, but am I the only person who finds it rather odd that Nezha is a villain in this movie and the hero in Nezha Conquers the Dragon Kings? There seems to be a bit of inspiration from The Adventures of Prince Achmed, particularly with the style of the layered backgrounds, the shape shifting battle sequence, and the aura around Sun Wukong after the mountain crumbles which looks like the effects of Aladdin's lamp.

There's also the English dub of the later movie, Nezha on Youtube, though it has some major changes from the Chinese version. It's easy enough to find with a one word search.
