I cannot think of one single thing that I would change about this film. The acting is incomparable, the directing deft, and the writing poignantly brilliant.
Like the great film, it's made with a great deal of visible affection both in front of and behind the camera.
This film is so real. It treats its characters with so much care and sensitivity.
