Hard disagree. All the examples you gave are anime with the exception of Stranger Things which suggests a rather narrow view of content.
It isn't that good stuff doesn't exist only that a majority is derivative and uninspired. Anything that does catch a spark is milked dry.
It blows my mind that anyone can consider Stranger Things to be great anything. It's utter dross. It's like our standards have dropped massively over the last 50 years in almost every way, in literature, music, journalism, politics, movies, and TV.
> majority is derivative and uninspired
A lot of good creations are derivations or remix of older ideas and they don’t have to be uninspired: West Side Stiry, Ulysses, so much of jazz music…
