HyperNormalisation (2016) by Adam Curtis/BBC - Impossible to put into words, except to say "must-watch." Seriously, just give it a chance. An extremely meta view of why things are the way they are.

If you love documentaries, you really owe it to yourself to check out Adam Curtis' documentaries. I think this might be the best place to start.

Description from the YouTube video: The cult documentary maker explores the falsity of modern life in his own inimitable style. Though he’s spent the best part of four decades making television, Curtis’s signature blend of hypnotic archive footage, authoritative voiceover and a seemingly inexhaustible appetite for bizarre historical tangents is better suited to the web, a place just as resistant to the narrative handholding of broadcast TV as he is. He argues that an army of technocrats, complacent radicals and Faustian internet entrepreneurs have conspired to create an unreal world; one whose familiar and often comforting details blind us to its total inauthenticity.
