Earlier quoted context omitted.
I don't see how it is not possible to make good product for both. That is the fans and general audience. Appeasing the later is pretty low bar. Instead it seems that shows are aimed at the vocal non-fans at social media.
The opportunity cost is there to prevent that, and the tastes of the fans don't always coincide with the general audience.
I'm not saying make a product for only the fans. But stay honest to source or previous material.
