I found it flabby - overall needed to be trimmed by about 15 minutes.
Also that damn cello! I get that it's depressing and sad and everything else. But by the 5th time it came on, I was ready to throw things at the screen. There's plenty of other instruments/ways to signify that.
The actors were terrific though.
I'd give it a solid B - I expected better.
cello is my favorite string instrument so i didnt mind
and yeah it felt like a longer directors cut of the film (which i also didnt mind)
