Grave of the Fireflies (1988 movie)

i watched it today. man this is a depressing story. describing the war in japan and the brother and sister became orphan and finally little sister died of malnutrition. it's more like a documentary. it's trying to tell the true event that happened during the war time. buildings being bombed and people escaped from their homes to the shelters. food is scarce and i think the story cannot go on if they stayed in the aunt's house.. just the brother is too stubborn and the aunt is over reacting. war brings destruction but war is still happening.
