Like, why wouldn't people be interested in knowing that the African slave trade of the colonial period actually started with Jewish kids, but they all died in the African climate of Sao Tome, so the Portuguese started buying slaves from the Congolese, which they captured from neighboring tribes, to work the fields??
It's so good. I've written more about it both in discussions and my own anime journal notepad than almost any other show. It's the only show where I consistently had new OH SHIT moments months after finishing it. It's the one show I've seen that actively challenges the viewer to process what they're seeing and hearing, and doesn't explicitly tell you "this is the bad guy, he's doing bad things." I want more shows like it
