Grave of the Fireflies (1988)

Grave of the Fireflies (1988) remains one of the most devastating war films ever made, using 1,400 hand-drawn frames to follow siblings Seita and Setsuko's struggle in WWII Japan. The film's unflinching depiction of starvation uses a 0.5% sugar cube ration as a recurring motif, a concrete cruelty that outperforms the typical war movie's battle scenes.
