I think this is ignoring the problem of the global market. Studios found that it was more profitable to cater to multiple countries and cultures simultaneously.

For example, even if 100% of America went to see a film, that only represents approximately 1/3 of China's population. As a studio, ignoring that market would be seen as throwing away money. So you will see immense pressure to make your movie marketable in China as well as America.

Even if many American consumers choose to watch a film catering to them that studio would still be pressured to view that film as a commercial failure.

It doesn't seem to matter so much what the local consumers want since their demand is dwarfed by global demand.
