On the other end of the spectrum, the Disney+ library is rather small, but I find at least half the shows to be enjoyable, so that's where I turn to first.
I've found a much better model is friends or critics' recommendations cross-checked against Rotten Tomatoes and IMDb ratings. (Which implies you need some people to use the scattergun approach, but I'd rather not be the guinea pig).
This way it doesn't matter if good Netflix shows are "needle in a haystack".
I guess it's down to how you frame it? Some people see 100 different flavors of ice cream. I see 100 different flavors of chocolate ice cream. Both perspectives are accurate. Which one is more useful to you perhaps depends on how much you like chocolate ice cream.
