Edit: I agree Netflix has good Originals. But most are from the early days when they favored quality over quantity. It is sad to see that they reversed that. They have much funding power and should give it to great art that really sticks, has ambitions and something to tell, and values my time instead of mediocrity.
Don't look at only series. They also have recipes repurposed. But they acquire good titles and also produce some good ones.
In the US, it's mostly their own productions and older content they explicitly acquired, but elsewhere, especially in markets that don't have a local HBO or Disney streaming service, they have incredible backlogs.
I remember finding basically everything I could wish for on there when traveling in SE Asia almost a decade ago, compared to a still decent offering in Western Europe, and mostly cobwebs in the US.
