From Uncle Francis:

After thinking the movie over this afternoon, it is a good movie after all. Writer & director Alfonso Cuarón is telling us about a woman’s story – mostly sad without explicitly saying so.

Namely,
1. mistreatment & abandonment by her boyfriend;
2. pain of losing her baby before birth; and
3. camaraderie of humanity irrespective of the race & age as depicted by saving two children from the sea.

I especially liked the last scene after rescuing two young children abd getting holding shoulder to shoulder with children around the bonfire.

I think it may win the best picture academy award – a beautiful cinematography anyway.
