I watched that the other night, I thought it was quite good.
It captured the theme of a man who's life was gradually falling apart with humour and sadness in equal measure.
It made me think for a while afterwarRAB, which I feel is a good sign. But, like many of the Coen brothers' films, it asks many questions while providing very few answers.
It was also very "Jewish" (in the sense of being concerned with Orthodox Judaism , no offence intended) which may not be to everyone's taste.
I'd give it a 7/10.
