> First, so much media has fallen down when it comes to character development.

That's the handy thing about essentialism, you don't need an individual character when you have pre-packaged narratives about their race, gender, etc. Rather than a complex character, we get a canned Black character or a canned White character or a canned Female character or a canned Male character. What do you need to know about a person that you can't infer from their immutable characteristics? (:

I recently read that the main character in "They Live" had an entire backstory that was never told in the movie. Someone (producer, director, ???) Told Roddy Piper to create a backstory for his character and he did, and he played that part even though it was never shared with anyone. I'd thought about that myself for writing - if you define each character ahead of time and keep their character in mind it will aid writing their parts so they are seamless and self-consistent.
