Though rendered a bit heavy-handedly for such an abbreviated film, the metaphor is nevertheless a clever way to talk about San’s struggle to understand her role in service of a country demanding unquestionable loyalty in the face of death and terror.

A war film and coming-of-age drama that's sugar-coated and bites off more than it could chew while failing to pack an emotional wallop.

B-

It succeeds as a powerful illustration of the horrors of war and an impressive calling card for new animation studio Sasayuri. As an adaptation, it's a bit more questionable.
