I love documentaries, but you have to realize you are getting just one point of view. There used to be a documentary web site, not sure if it’s around anymore. I found a great history of Islam by Jim Al-Kahlili. Richard Carrier later straightened me out a little bit, but it was pretty accurate.
I just flipped on Netflix the other day and found their new “Nobody Speak”. It connects some rich people, including Trump to an effort to suppress the press, going so far as to buy up newspapers change the staff over to their point of view.
