San and Mayu attend an all-girls school on a warm and tranquil island. When war reaches their shores, they are ordered to help nurse the wounded in a military hospital hidden away in a cave. Amidst escalating death and brutality, the friends struggle to find solace in their fragile lives.

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.

I was very moved by it. So impressed they could tell this story in such a succinct way. Great debut for the studio and director

The brevity of cocoon is a demerit to the story it’s trying to tell, despite the heavy subject matter it depicts.

Cocoon earns its place as a quintessential anime not only for the difficult conversations it brings to light about girlhood being a special kind of hell during wartime, but for the unwavering hope it harbors that such events may never happen again.

Everyone imitates Miyazaki, everyone yearns to make another Spirited Away, and cocoon certainly comes closer than most in that regard... But Ina, ultimately, is not Miyazaki.

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.

Beautiful, beautiful but very sad movie - more tragic than even "The Cave of Fireflies". Short run time ( just about 1 hr) is a plus - it's a maximum one can endure watching hardships of war.
