If you loved Slam Dunk: The Movie, try The Wild Swans
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 Nobutaka Nishizawa, and they sit in Animation / Drama territory. If that's the register that drew you to Slam Dunk: The Movie, the second film will land in a comparable space — through a different lens.
What The Wild Swans is
Pity the siblings turned into swans, but pity harder the poor girl condemned to crochet poison ivy sweaters. Six years disappear stitch by stitch. The sorceress may hover off-screen, but her shadow clings to every needle.
