PBS is out here posting the most harrowing and heart-wrenching documentaries totally free to watch on YouTube
Natchez is a masterclass as just letting people get comfortable talking to you and talking to the camera because honestly, it didn't take much before they would just start saying the quiet part out loud. There is a moment close to the beginning where the white Reverend guy clearly thinks that he is doing multiple takes that they will cut between so that he can find the most politically correct phrasing, but they just leave the one continuous take in and it is just beautiful
Also the section on the punkah wallah is just masterfully edited and the park ranger is such a beautiful orator. His story telling and delivery are just stunning and really lands those gut punches of the reality of these antebellum Big Houses that the white house owners would rather just gloss over
