There is also The Criterion Channel where I saw La Jetée for the first time after years of reluctance to immerse myself in a film essentially made of still photos. I have now gone back and watched it three more times, both in French and English. That’s how large of an impact it’s had on me. And I originally meant to get through it quickly (28 minutes duration), in preparation to rewatch 12 Monkeys.
Netflix does show some films that cater to a non mainstream audience, but may take more effort to find them. I recently saw Aftersun directed by Charlotte Wells, and I can’t recommend it highly enough. You will sob quietly.
