If you loved Pokémon Ranger et le Temple des Mers, try Pokémon 4Ever - Celebi, la voix de la forêt
Un pont entre un film que tu as déjà vu et un que peu de gens ont croisé. Voici ce qu'ils partagent, et ce que le second fait que le premier ne fait pas.

Pokémon Ranger et le Temple des Mers

Pokémon 4Ever - Celebi, la voix de la forêt
Ce qu'ils partagent
Both films are directed by Kunihiko Yuyama, and they both carry the cozy mood tag, and they sit in Adventure / Animation / Family / Fantasy / Science Fiction territory.

What Pokémon 4Ever - Celebi, la voix de la forêt is
Here's a movie about the sanctity of friendship, if you're into that sort of thing. A time-traveling Pokémon and its new human pal must team up with Ash and Pikachu to save the forest from an encroaching threat. At least the title doesn't lie; this probably will last 4Ever.
