In Hollywood, story content of movies follows a hierarchy of power, not the relative quality of various ideas. Hollywood does not lack for quality writing. It's just that quality writing commonly has to be sacrificed in order to propel a film into production. A studio needs a star and a director to make a film, so those are the folk who'll define the content. If they don't have the same creative sensibilities, then the content will change.
