Carl Hudson’s review published on Letterboxd:
Someone should give that cat an Oscar. And, actually, nominate it for a ton of more stuff. What the fuck, people who nominate films?
Anyway, the Coen-brothers keep knocking them out of the park. Having gone from a Chekov, clockwork-type of storytelling, where everything is foreshadowed, set-up and payed off - where every gun goes off and nothing ever misfires, they dropped everything to make A Serious Man. From that point, it seems they've started making films without premises - where before it was "the crime caper", "the roadtrip", "gangsters", "the western" and so on, we now have... a movie about a musician. And it rocks. (pun intended)
Marrying their Chekov-principles with A Serious Man's colour palette and methodology, Inside LLewyn Davis is a masterpiece. It's hurtful, it's dark, it's funny, it's heartwarming, it's wonderful.
Fantastic. Keep at it, Coens. I have no idea what you'll do next, but I can't wait to see it. I have no doubt it'll be great.
