I realize I am late to this movie. There is nothing I can say that is not contained in the NYTs review by A O Scott.
If you've not yet seen the movie, go. It's excellent. Not just the story, which is wonderful, but the cinematography. It's still in theatrical release in Saint Louis at the Landmark Plaza Frontenac, but I can't imagine it will be for much longer.
Note: This post has been correct to reflect that it is A O Scott at the NYTs who reviews movies.
