Further, it seems like there are a number of people unhappy with the homepage UI, which may be tangentially associated to recommendations. When the same things keep getting recommended in multiple categories for several months, it gives the impression the library is even smaller than it actually is.
Personally, in terms of UI, especially regarding player functionality, I would take Netflix over Hulu and HBO Max every time. But, I am slightly bitter about them replacing the 5 star rating system with a two star system and now a 3 star system.
