It was made a couple of years ago, but Defuncland's "Disney's FastPass: A complicated history" is an incredible documentary that I watched this year. You don't need to know too much about Disney for it to absorb you in.
The Alpinist was incredible. There’s a scene where Marc Andre climbs an ice wall, alone, in silence. Just the crackling of the ice, his breathing, and the sound of his icepicks and shoes. Made me understand the “why” - without any words.
