Well see there are whole bodies of academia that have been devoted to critically analyzing media and how it intersects with society, just quantifying numbers and crudely applying the benchmark doesn't really tell you the full story and if I need to point that out to you, you desperately need a more well rounded humanities education.
You can "hit the numbers" so to speak with a movie for diversity and do nothing for actual representation if you undermine and hamstring the representation of diversity and bottle it up as secondary to the story, or do the opposite and repeatedly elevate diversity as an inherently tragic narrative.
