Pokémon 9: Pokémon Ranger und der Tempel des Meeres

Pokémon 4: Die zeitlose Begegnung
Was sie teilen
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. If that's the register that drew you to Pokémon 9: Pokémon Ranger und der Tempel des Meeres, the second film will land in a comparable space — through a different lens.
What Pokémon 4: Die zeitlose Begegnung 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.
