If you loved Pikachu & Pichu, try Camp Pikachu
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 sit in Adventure / Animation / Family territory. If that's the register that drew you to Pikachu & Pichu, the second film will land in a comparable space — through a different lens.
What Camp Pikachu is
Here's a film about the importance of being on time, I guess. After being flung from a train, two Pichu enlist Pikachu and company to help them catch the next one. It's a slight tale that probably delighted its target audience.
