I dont know, most Americans are too lazy to watch a movie with subtitles.
Most dubbed Chinese movies I have seen are almost unwatchable. Even the movies that were described as classics.
There are plenty of excellent dubbed Chinese and Korean Films, and given a choice between straight entertainment and some Hollywood dreck promoting one genuinely vile sexual practice or another, or cartoon "right-wing" villains (or both), about half the viewing audience would prefer the former.
