This is one of the best documentaries I've watched in quite awhile. It was heartbreaking, fascinating (seeing the earth do things it normally doesn't do), and, like other reviewers have almost unanimously said, the most heartbreaking of all was the Thai boy who lost his mother and sisters. I wonder if his "interview" was so sad because it was so difficult for him to show emotion, yet we were still able to see he was deeply affected by his losses.
Every one of the people interviewed had a heartbreaking story to tell, yet all of them showed a courage not usually found in society in general. The loss was just unreal!
One thing I noticed, and which made this movie much more sad, was the lack of hope in some of the adults (even those who adhered to a religion) concerning the fate of their lost children/grandchildren after death took them from this life. It was in striking contrast to what the Messianic faiths teach: that because a man, both divine and human in nature, was sacrificed and resurrected, we have the assurance we will live on after we pass in death from this life, and not only live, but live a better life then we can now comprehend.
These are the kinds of movies we need to be watching in order to develop more compassion for the lives of others, and as Leif Thor pointed out, we also need to develop an educational program to be as best prepared as possible for the inevitable disasters that are still to come.
