Beautiful animation - generic story.

I loved the space exploration theme (reminded me of the movie Explorers) but it was kind of forgotten almost immediately after she got there, and instead of being on the moon she was in strange alien rainbow city instead.

the story felt like it barely made any sense, and most of the characters felt a bit cliched (only exception maybe Chang'e); the moral theme was good though, although maybe it was borrowing quite a bit from Inside Out, where (spoilers for that I guess) the goal of the main character is misguided, where getting what you impulsively want is not the correct solution, but accepting your own feelings of sadness and loss is what you need to do.
