You probably already know about Dogme 95, but for anybody who doesn't: https://en.wikipedia.org/wiki/Dogme_95

I can imagine more ideas of purity like this emerging as a consequence.

I had seen Dogme ages ago, thanks for reminding me. Agree we may see more like it, but probably with about the same cultural relevance : mostly a footnote.

Amazing.

This reads like a Nuzlocke Challenge for cinematography.
