The expectation was a white produced IP with black protagonists, which is what they got. Very different from their idea of the mermaid as a white young girl. And Black men tend to be more accepted in East Asian media than black women in general, like Hyunmin, Sam Okyere, Jonathan, Jerry in Korea, but fewer recognizable black women.
The female protagonist in Black Panther was the most popular character after the main character buddy....also TLM knew that China/Korea would not enjoy it mainly because the special effects are not up to Avatar's par and the animatronic characters have been changed.
Korea only took to Aladdin because of Speechless and it became the biggest #1 hit. Beauty in the Beast underperformed in Korea, forget TLM. If anything China being unresponsive is the bigger loss because they had no hope for Korea, but China has far better movies going on right now so BO comparison is touch. Suzume absolutely washed kids markets recently.
TLM will do great in America, decent in the Phillipines/SEA and not great everywhere else.
