Query: An emotional earthquake.

This film shook me by the roots. It's a documentary style film with plenty of details, images, recaptured moments of streets, events, people, a really stunning work by the director and he manages to evoke the most sensitive specific feelings for people you didn't know until a few minutes ago.I was not as shocked as I was shaken and overcome by grief and remorse the film-maker arose in me.It will not be wrong to say that this is the most powerful film I've seen and every bit of it is true.No lack of irony. I did not stop weeping. Somebody said that when people die we always talk good about them but in this case it was true. Do give this is a viewing, fifteen minutes into it, you'll forget what you were up to earlier. Thanks.
