I loved the first 20-30 episodes, but at a certain point I got the feeling they had a very significant axe to grind on their supposedly impartial revisiting of some of the events they were looking at.

When they started talking about health outcomes, especially, their tone of "we know what's obviously true, our outgroup is stupid" got too strong for me and I stopped listening.

I'd be interested to know if they've toned that down, at all.
