There are three great war movies. This film is at the top of the list. You will not be able to get these images out of your thoughts. I would not categorize this film as anti-war; rather, I'd say it takes a realistic look at the battle/conflict it portrays and does not flinch at failing to romanticize any part of the story. You might see the narrator's story somewhat romantic, but the loss suffered here justifies the actions of the character. All in all a brilliant story of war like you have never seen it before. The story also examines bureaucratic Japan after the war that's where the story really packs a punch.
There is beautiful scene involving a last meal that puts this writer/screen writer and this director at the top of my list. Great movie.
By the way, the other two great war movies are, "Battle of Algiers" and "Queimada."
