Go to this YouTube channel: Kino Lorber, click Playlists and then view the Free Documentaries (80 feature-length films) or the Free Movies on Demand playlist (145 films.) Kino Lorber is an international film distribution company; I thought it was a person when I first heard mention of this.
Now try this experiment: Pick a documentary (try Filmworker if you know who Stanley Kubrick is, M.C. Escher: Journey to Infinity if you have eyes, or Hieronymus Bosch: Touched by the Devil if painting is more your thing.) Watch the movie. Then reflect on the experience of watching a feature–length documentary, versus say, modern “serial” shows. I’ve relearned just how bad modern entertainment can be, when I reminded myself just how good film can be. (Surprise bonus-round: Watch The Atomic Café and be gobsmacked, horrified, and… some-other-feeling-I-can’t-quite-find-the-right-word-for in repeated cycles.)
