I also watched that Matt Walsh thing. A little vomit-inducing, but a great example of manipulative documentary techniques ("experts," scary music, "gotchya" ambush interviews).
I usually consume a number of documentaries, but this year I think I only watched...
Frozen Planet II
Fake Famous (2021) https://www.themoviedb.org/movie/788610-fake-famous
Do YouTube documentaries count?
'Contrepreneurs: The Mikkelsen Twins' https://yewtu.be/watch?v=biYciU1uiUw and 'Line Goes Up – The Problem With NFTs' https://yewtu.be/watch?v=YQ_xWvX1n9g by Folding Ideas were great.
And not a documentary, more of a biopic, but the Ramanujan movie "The Man Who Knew Infinity" was pretty good. https://en.wikipedia.org/wiki/The_Man_Who_Knew_Infinity
This was one of the best documentaries I've ever seen. Even if you don't care for the Apollo missions, it's just so well done it deserves a watch. It's less than an hour and a half.
