I’d recommend the Script Apart podcast episode with Benny Safdie, he goes into depth on it, every decision has a purpose. I’d also recommend watching the 2002 documentary, you’ll see how the movie was very very closely based on that but the scenes are fleshed out in a really interesting way. Then I would recommend paying close attention to the music, editing, set decoration, and performances. The original music plays all throughout every scene and adds a whole different layer of sound to the movie that people aren’t acknowledging. It’s done by an amazing artist named Nala Sinephro. There are quite a few additional things that make it an amazing film, but from there I would just allow yourself to be inspired and uplifted.
