I actually liked this way more than anything Disney or Pixar has put out recently (COCO the possible exception).
Strong emotional storyline and beautiful imagination and art design in the moon sequences. Really appreciated, too, how steeped the movie is in Chinese culture and mythology. It felt unique and affecting. My kids already want to watch it a third time, they loved it.
Weak point is definitely the musical numbers, aside from maybe "Rocket to the Moon" and "Ultraluminary."
