Lack of good storyline.

This is a tender, generous movie that likes its characters and presents them as real people, full of flaws and strengths.

I was totally surprised at how great this film.You could feel your paranoia rise as the film went on and as you gradually learned the details of the real situation.

This is one of the few movies I've ever seen where the whole audience broke into spontaneous, loud applause a third of the way in.
