I’d say the Coen brothers are the most consistently good filmmakers.

There’s absolute bangers like Fargo and True Grit. Even their lesser known ones like The Ladykillers and Hail Caesar are worth a watch.

There’s O Brother Where Art Thou, and Barton Fink, which are their most underrated in my opinion.

I don’t think they put out a single stinker, and most are A or A+.
