Can I say Black Panther is ridiculous? Maybe Americans thought it was perfectly normal to depict Wankada like that, but let's imagine a similar story about China:

China is a closed society with a highly advanced civilization and a technology level that surpasses the rest of the world. The country is ruled by tribal chieftains who use swords, spears, and what not to fight for the title of supreme leader. All Chinese people are passionate about foot-binding. The chieftains living in the palace are extravagantly rich and the level of medical technology is almost miraculous. The magnetic levitation trains are like magic. IN the same time, ordinary Chinese people live in huts and spend their days feeding rhinoceroses (or, to fit the local customs, pandas) since there are barely any roads in the country.

If you were to show this movie in China and say that it praises the Chinese people and culture, I'd say you're insulting.
