The International Documentary Association presents its list of the top 25 documentaries chosen by their members, and sponsored by Netflix. According to IndieWire,
"Online movie rental service Netflix is on board as the presenting sponsor of the program, facilitating sceeners of the films for voters and also making them available to subscribers of their service. The company indicated that the majority of the 700 films on the original ballot are available on their service, with the exception of #19, Frederick Wiseman's "Titicut Follies," which has never been released commercially and is only available for educational purposes."
I've seen all but nine of them. Too much Michael Moore, if you ask me. He's not a documentarian; he's a propagandist. However, I shouldn't be surprised. The documentary genre has always been dominated by the Left. By definition, conservatives seek to preserve the status quo, or even reverse so-called "progress." The Left seeks to disrupt the status quo. Provoking change is the motivation behind most documentaries. Hence, the correlation.
