I would say: 1. No Country for Old Men 2. Fargo 3. Blood Simple 4. Miller's Crossing 5. A Serious Man Honorable Mentions: The Big Lebowski and Barton Fink.
1. Blood Simple 2. Miller's Crossing 3. Fargo 4. No Country 5. Hudsucker Proxy Overall, I have mixed feelings about Coen Bros. films, but the 1-3 films on my list are masterpieces IMO.
No Country is a masterpiece as well. But I agree with Miller's Crossing, Blood Simple, and Fargo also being masterpieces, so they have 4 masterpieces.
1. No Country For Old Man 2. Raising Arizona 3. Miller's Crossing 4. Fargo 5. The Man who Wasn't There
Fargo and then Raising Arizona are my favorites. Need to rewatch their movies, but I’d guess the rest of the 5 would be No Country for Old Men, Blood Simple, and Miller’s Crossing
Raising Arizona, Miller's Crossing, No Country for Old Men, Blood Simple, Barton Fink Hon mentions: Big Lebowksi, Fargo
