Llewyn Davis from the title is an American folk musician who seems to have had some success when he still played with a partner, but solo things are fairly low. We see Llewyn struggling through life, heavily leaning on people he knows.
“Inside Llewyn Davis” is not of the Coen-comedy-type. Rather it is a drama with a subtle sense of humour which is not all that present.
The film is amusing, but not one of the better Coens.
