I was just about to say this. They usually get worldwide success with authentic local language films and shows that don't try so many other languages like English but still think including American actors and English language scenes is necessary for global success.

I have the same problem even with Europeans such as German and Norwegian filmmakers who don't realize how awkward it is when they force in English scenes. The delivery is usually not right and doesn't feel as smooth as when they use the language they're comfortable with.
