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.
