If you loved The Door Into Summer, try Barefoot Gen
A bridge between a film you've already seen and one most people haven't. Here's what they share, and what the second one does that the first one doesn't.
What they share
Both films are directed by Mori Masaki, and they both carry the bittersweet mood tag, and they sit in Animation / Drama territory. If that's the register that drew you to The Door Into Summer, the second film will land in a comparable space — through a different lens.

What Barefoot Gen is
You live in Hiroshima. World War II ends with a flash. But survival means scavenging, and more hardship. Then sickness spreads. Yet people find joy. Mori Masaki's film softens its visual style; the story's core remains stark.
