I've got a friend who is a fact checker for a Hollywood studio. He says the only facts the suits care about are ones that get them in trouble with the legal department, that could get them sued. Nothing else matters.

Things like that capo are doubly annoying because they got it RIGHT in one scene.

Just enjoy the cinematography and the story as a complete piece of fiction. I still think the Coen's were unsure what they really wanted to portray. Llewyn's malaise and confusion as to how he wants to spend the rest of his life could be explored as being a result of his musical partner's (and, I assume, friend) suicide. That would be a good story right there. And there's the whole comic side of the film that could have turned the film in a whole different direction.

And what DOES that loop of beginning and ending on Llewyn's (well-deserved) beating really mean?
