Both actors are amazing, especially the young girl. For a young actress to express such mixed emotions clearly is very impressive. The movie has a very rooted sense of place. I was at a Q & A with the director and it was clear she made a very thorough effort to choose locations and actors (professional and amateurs) with an eye for realism.
I only knock this story because the arc is fairly predictable. For an American movie there is remarkably little plot and no villain or hero. It was hard to decide between a 7 and an 8.
