Michael Offerosky’s review published on Letterboxd:
The Coen Brothers latest comedy-drama is sure to split audiences. One of the reasons this is is that not a lot happens in the film. Llewyn Davis (Oscar Isaacs) is a folk singer in 1961. The film is more interested in capturing mood and the music of the era instead of telling a story that grips. Fans of the Coens will take to this more than those not initiated. There's a lot to like here though, the performances are all good including Carey Mulligan, Justin Timberlake, and the title role played very well by Oscar Isaacs. The songs seem authentic to the time. There are things that Coen detractors will jump on and one of those things is some bizarre turns that the story takes. These twists don't add up to much. Another problem is that the film has many loose ends which don't get tied up. So what does one think of INSIDE LLEWYN DAVIS? It's hard to tell what will be the ultimate verdict from audiences on the film. Early critical evaluation has been overwhelmingly positive. Does that mean the critics are right on this one? Too early to say but this may be a film that grows upon rewatches. As it stands right now in this reviewers eyes, this isn't among the best of the Coen brothers but it's far from their worst. This is a film that has a lot going for it, it's just one wishes more was going on in the film itself.
