Note, I am not saying American films are the best, I am just saying that film quotas make it easier for mediocre films to be exhibited because they aren’t competing against a full slate of imports. Look at the current French film industry as an example — pretty much crap except for the occasional standout. Although to be fair, the quota system in Korea actually resulted in a pretty vibrant cinema industry, but that seems to be an exception.
They don't need a given series to be a smash investment if they control the actors/actresses/clothing choices/product placements, etc.
The great thing about films like that is that if they do age, they age very well, and there are hundreds of films by auteurs you'd probably enjoy.
AFI Top 100 movies, the Criterion collection, or just going through a director's previous films.
If you liked Dunkirk, have you seen the Band of Brothers TV series?
I highly recommend checking out a film festival if you like seeing original films. Most film festivals only show movies that have yet to be public. There are hundreds of movies a year that are shown at film festivals and never seen again.
If someone would provide a streaming service that cared about video quality, even basic things like compression artifacts, I'd pay more for it.

* Sorry to bother you
* Leave No Trace
* Eight Grade
* The Rider
A film that can combines fun and avant-garde is a rare thing, and it does so brilliantly.
