I expected the charm and fuzzy feelings, but not the nuanced, topical take on immigration, delivered with the utmost efficacy. Bravo!
It's all very wholesome and hard to criticize, though I think it could have benefited from some more Spirited Away -style bittersweetness, and a more complex antagonist. But hey, it works.
Sidenote: the wonderful art direction somehow reminded me of Spielberg's Tintin and, in contrast, how much of a disappointment that was.
