If you loved Doraemon: Nobita and the Green Giant Legend, try Children of the Sea
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 Ayumu Watanabe, and they sit in Adventure / Animation / Fantasy territory. If that's the register that drew you to Doraemon: Nobita and the Green Giant Legend, the second film will land in a comparable space — through a different lens.
What Children of the Sea is
Coastal town. Summer. A child's lost baseball. Adolescent Ruka meets two strange boys from the sea. Supernatural mysteries bloom around the trio; sea creatures vanish, then reappear far from home. Watanabe's anime is eco-conscious and visually striking.
