I sometimes wonder if someone at the top is trying to drive people away from TV/film/video. Yes there's more content than ever before but as regards drama etc. the writing is generally dreadful and the stories lack originality, on YouTube the adverts are becoming obnoxious and if extremely one-sided political messaging isn't to your taste, well, good luck finding a single programme that isn't stuffed to the gills with it.
YouTube adverts have been obnoxious for a long time, but it's got far far far worse this year. Unfortunately, I think it is necessary to support the media industry thanks to the diminishing returns from sales of music/film due to the proliferation of "art is disposable and very cheap" $9.99-a-month streaming services, plus the fact that every new album ends up on YouTube within a week these days as an "entire album" upload.
The sheer amount of content available these days is probably what you are noticing regarding dramas / films; I can remember very few decent Hollywood films recently as utter garbage seems to make billions of dollars, so the studios believe it's what people want.
It isn't a new issue though - "Penny Dreadfuls" were the old poor-quality entertainment of yesteryear where I suspect people were saying the same things that we are saying now. The only difference now is the availability of immense volumes of instantly accessible tripe.
As for political messaging, I am entirely apolitical but do see a lot of ideologies being promoted/pushed in programmes, with an opposing stance on any "modern" issue descending rapidly into a shouting match instead of a reasonable, logical debate; it then turns into a witch hunt regarding the opposing party's behaviour instead of a balanced discussion of the first issue raised. Exercise your free will and turn the rubbish off like I do!
