If you loved Pokémon Mystery Dungeon: Team Go-Getters out of the Gate!, try Pokémon 4Ever
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.

Pokémon Mystery Dungeon: Team Go-Getters out of the Gate!

Pokémon 4Ever
What they share
Both films are directed by Kunihiko Yuyama, and they both carry the cozy mood tag, and they sit in Adventure / Animation / Fantasy territory. If that's the register that drew you to Pokémon Mystery Dungeon: Team Go-Getters out of the Gate!, the second film will land in a comparable space — through a different lens.
What Pokémon 4Ever 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.
