It's good. And quite harsh. Very nicely written, I thought. The ending isn't as strong as bits of the middle, but I can't think of much else wrong with it.
I came out of it feeling slightly dissatisfied and I think that's it, the whole film is so powerful until the end and while it couldn't really have ended any other way it just doesn't quite live up to the rest.
Yes. On the other hand, possibly they considered a tightly resolved Hollywood ending and thought something a bit less tidy was better. Don't know.
