Pokémon: Giratina and the Sky Warrior

Pokémon: The Rise of Darkrai
What they share
Both films are directed by Kunihiko Yuyama, and they both carry the cozy, playful mood tags, and they sit in Adventure / Animation / Family / Fantasy territory. If that's the register that drew you to Pokémon: Giratina and the Sky Warrior, the second film will land in a comparable space — through a different lens.
What Pokémon: The Rise of Darkrai is
Nestled in rural tranquility, the village’s calm hides a pocket universe of impending cosmic kerfuffle. Traveling trainers find time itself bending when a shadowy stranger named Darkrai drifts into town with two ticking time-bomb deities in hot pursuit. Perfect antidote for anyone who’s ever worried their vacation photos might warp reality.
