If you loved Doraemon y la guerra de las galaxias, try Doraemon Atlantis: El castillo del mal
Un puente entre una película que ya has visto y una que casi nadie ha cruzado. Esto es lo que comparten, y lo que la segunda hace que la primera no hace.

Doraemon y la guerra de las galaxias

Doraemon Atlantis: El castillo del mal
Lo que comparten
Both films are directed by Tsutomu Shibayama, and they both carry the cozy, playful, uplifting mood tags, and they sit in Adventure / Animation / Family / Fantasy / Science Fiction territory. If that's the register that drew you to Doraemon y la guerra de las galaxias, the second film will land in a comparable space — through a different lens.
What Doraemon Atlantis: El castillo del mal is
Here's another Doraemon movie, doing what they all do. Nobita and his pals embark on an underwater adventure in the Pacific. The bully, Gian, and his sidekick, Suneo, steal Doraemon's submarine to hunt for sunken treasure in the Atlantic. It's another entry.
