The Coens are probably my favorite filmmakers, with True Grit being my favorite of theirs. It has an amazing cast, sublime landscapes, and an incredible revenge/coming-of-age narrative in which all the characters have believable motivations and clever dialogue.
It’s hard to pick, but what do you think?
Big Lebowski and O, Brother
Not even close imo. Hail, Caesar kinda sucked and was boring imo.
