Joyce Heinen’s review published on Letterboxd:
Llewyn Davis is a homeless singer songwriter fighting for his life as a musician. In a journey from one bar to another, he meets various people that all don’t know how to deal with the desolate songwriter. The film comes to life when John Goodman, as jazz musician Roland Turner, enters the story. With his sharp observations and arrogance he manages to illustrate the clash between folk and jazz in a hilarious way.
To make this movie not a standard film about music, the Coen Brothers added some typical Coen elements. Genius dialogues, intimate songs and perfects shots. Especially an absurd studio session where Llewyn joins a satirical evocation to president Kennedy, it has a definite Coen signature on it.
Oscar Isaac us very good as Llewyn Davis and he has a surprisingly good singing voice. The movie is not perfect, but The Coen Brothers made a great film. They can make a great story with the simplest material.
