If you loved Pokémon: Lucario and the Mystery of Mew, try Pokémon: Destiny Deoxys
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.
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: Lucario and the Mystery of Mew, the second film will land in a comparable space — through a different lens.

What Pokémon: Destiny Deoxys is
A spacefaring Pokémon crashes into a cityscape, locals panic as it warps reality. A boy and his team try calming the intruder’s chaotic energy. City gets a new skyscraper out of the deal.
