Everyone's an edge case
Something Netflix has figured out (and many streaming services are picking up on) is that there is no average user.
That of the thousands of things to watch on Netflix alone, a single viewer will only watch less than 5% of it all. And, at the same time, no two viewers will watch exactly the same things.
Sure, two people with the same psychographics may watch the same show on occasion, but more often they'll watch different shows in different genres or sub-genres. (And probably on different platforms as well.)
This means two things:
The way to 'win in at streaming' isn't to cater to a mass market. Because there is no mass market.
Catering to everyone is a surefire way to fail. Because in an age where you can watch anything and everything in your pj's, making average movies for average people no longer works.
Understanding that the folks watching Stranger Things are not the same as those watching Bridgerton, or Chefs Table, or Black Mirror, or Blood of Zeus, and vice-versa, is the first step on the road to creating something original.
Choosing an audience and making something truly unique for them is the second.
