I have Netflix and enjoy Stranger Things, but I also watch old programs and movies I haven't seen or want to see again.
They rotate their schedule (i.e., get rid of TV shows or movies), so I've occasionally lost out on seeing the end of series I didn't "binge watch " before it went away.
I suspect the Disney channel will be a a major competitor in the industry, not only for the kiddie audience, but for the Star Wars and other franchises they bought that presumably won't be available elsewhere.
I never subscribed to HBO, despite paying to watch some current movies, so I'm not in that demographic.
