I disagree. If you are making a show about wizards which will be aired on Netflix, you know that the target population are those interested in magic. Hence, you can create a more complex and detailed story/plot, characters, settings and so on, because you know that those watching are more interested than the general public.

They are also likely to be less forgiving if they expect a show about magic created by others also interested in magic. A show about magic aired on Discovery Channel on the other hand is likely to be superficial, lacking of deeper analysis or content, and laden with tons of repetition after every single ad break just to avoid confusing viewers with a three minute attention span.
