It seems to me...
I just saw this. (I almost always come in to look around after seeing a new film)
It seems to me that a lot of people on here think that Llewyn Davis was just a jerk who caused all of his own problems.
Interesting...
It seems to me that Llewyn was actually an extremely tolerant human being just trying to make it in a world that literally wanted to take a crap on him every time he was around.
It was like this guy could never catch a single break.
Everyone also seems to miss that the idea of the whole movie was that it was about this guy who is trying very hard to deal with the loss of his partner who committed SUICIDE. Guy didn't just die, his best friend and partner KILLED himself. That is ... extremely rough.
I immediately said (within the first like 20 minutes) "He's severely depressed...why does no one see this? He's severely depressed and desperate."
Everyone and everything just continued to hurt him. He tries, he tries really hard but nothing seems to help.
He literally does things that we would never ever do to go for his dreams. Sleeping on couches, trudging through snow, walking up to someone and asking to play for them, etc... and yet he can't get anywhere.
He loses it a few times with people because of his inability to deal with/ handle Mike's death.
The cat (as other people have mentioned) is a representation of this. He carries it around with him (also signifying that he IS a GOOD person)... and can't let it go.
Oh, and let's not forget that in the middle of all of this pain and loss and anguish and (Jean who honestly pissed me off beyond what I can even express) repeatedly calling him a loser and an @sshole. (if the roles were reversed, women would have been livid... he barely raises his voice at her)...
I see the ending as a mixed bag... which of course is what I think they meant. On the one hand, he got beaten up and left in an alley. On the other, here's Bob Dylan with his moodiness and his odd persona... just like Llewyn. I think there's hope yet.
