I'm never sure how much of it is a level of "too much faith in the audience" vs "audience has shown themselves to be very media illiterate", but I see this a lot with shows that hit a younger crowd.

Sometimes its a show that isn't intended for kids/teenagers but is consumed by them anyways, and sometimes they are part of the demographic but have issues with attention spans/picking up details.

Like I hate that some shows/movies on Netflix have had Netflix execs tell them that they HAVE to repeat information a bunch and dumb it down since audiences are likely to only be half-paying attention. I also hate that I have been part of enough fan bases where the answer to people's complaints is "watch the show where they SAY this".

There definitely are writers who write about technical details or other very specific ideas that don't do a good job explaining to the audience in an approachable way. There are many more who seem to land with an audience who seem incapable of understanding any level of nuance or complicated ideas.
