Yes, they have a quality problem. Part of the problem with the subscriber model is that these companies have to produce content to justify the monthly fees. This has led to overly long shows and movies. Stories that could have been told in 1.5 hours are now taking much much longer than needed.

A perfect example is Scorsese's "The Irishman." That movie could have easily been 2-2.5 hours yet it came in at over 3 hours. It was a detriment to the movie rather than a positive. Yet, I bet Netflix loved the extra content even though it was not a good thing for the movie.
