I somewhat enjoy Stranger Things but it's falling into the space where I can write the next line of dialog in my head for whole scenes. Whereas it started out poking fun at tropes like doing exposition or relationship development at moments of maximum danger it's turned into a long sequence of Obligatory Scenes that feel increasingly forced.
You're describing mainstream entertainment in general. I started noticing this with the storyboard-as-film, action-by-numbers "Raider's of the Lost Ark". (I won't even waste my time on super hero films.)
It tastes like bland mashed potatoes to me.
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.
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…
When I hear "there's nothing good available," I assume the person is a dullard. Like where are you looking that you can't throw a rock and hit something worth watching?!
