I have to applaud and second the reviewer who gives this film 10/10 and who thinks the current 6.9 average must be a result of many people not watching to the end. I think it's the result of many viewers not appreciating the art, subtlety, and deeply UNnationalistic message. In a country rife with jingoism, the message that no one is "right" when waging war (and especially commiting atrocity)will not be especially popular. After living three years in Japan, I can understand how American (and indeed Western)independence and confidence can be perceived as(and even sometimes are)arrogance and ethonocentricity.
The movie looks at what it means to be human and afraid. It examines how shame and cowardice haunt most men of noble heart. It reveals our commonalities to be undeniably more powerful and real than our transitory differences. It shows how truly stupid man must be to perpetuate the horrors of warfare and to mar his soul by using power to hurt others.
It's a 10/10 in my book, but realistically speaking, if most people agreed, well, there wouldn't be any grist for this mill.
