I finished watching this film two hours ago and the punch in the stomach I received watching it still hurts. I don't recall having received such a punch in my 60 or so years of film watching. Unlike films such as "Schindler's List" or "Empire of the Sun", this film does not take sides. It's like a candid camera operated by an invisible grand master hidden in the crowd or the rubble. It's just there recording events. As a result, despite the fact that it focuses on the big picture, the individual is not lost: Both the Chinese and the Japanese, each and every one of them, in huge crowds are real believable characters. This gives the viewer a grand and horrible sense of presence which is what makes it so painful. It would take courage to watch it again.
