Lack of good storyline.

Very interesting film. Was caught on the premise when seeing the trailer but unsure as to what the outcome would be for the showing. As it turns out, it was a very good film.

It's an amazing and heartbreaking story.

A lot of perfectly good film show their cards early, establish a unique premise and let the audience explore a topic at a leisurely pace, without much in terms of surprise. this film is not one of those films.
