Apart from outstanding animation (love the playoff part), good music and romcom, the film depicts migration because of natural disaster, how the migrants adapt to a new place and even elemental discrimination to an extent. The fire people live in a separate area apart from other elements, and I notice that the place is very outdated compared to the city of other 3 elements and also vulnerable to disasters as well. At some point the 2 protagonist find out about the cause of leaking water in the fire district, which is motor oil, and ngl this part is a bit lacking in depth. I wish they could venture more about this problem but maybe that would be too long. Moreover, the discrimination to fire people is very straightforward, with them forbidden from many places to the city with almost no sight of fire. I love that the movie also talks about generational conflict, especially in migrant families with the dilemma of your dream vs your family responsibility. The love of the 2 protagonist is adorable too, I enjoyed it a lot. All in all, a meaningful and lighthearted film to sit back and enjoy. Oh, and Wade is such a cool guy (get it?).
