I keep running into this idea from multiple sources:
The more specifically you are expressing your obsessions/vision in your art, the more universal it’s appeal.
Intuitively, you might think it would mean the opposite, but apparently you would be wrong.
Instead of appealing to less people, it appeals to more.
Maybe this helps explain why quasi-art by committee (think Hollywood films) is always the least interesting.
Films that conform to the very specific vision of an auteur (think Kubrick) tend to be the most interesting and culturally influential.
