If you loved Doraemon: Nobita and the Animal Planet, try Doraemon: Nobita and the Robot Kingdom
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.

Doraemon: Nobita and the Animal Planet

Doraemon: Nobita and the Robot Kingdom
What they share
Both films are directed by Tsutomu Shibayama, and they both carry the cozy, playful mood tags, and they sit in Adventure / Animation / Family / Fantasy / Science Fiction territory. If that's the register that drew you to Doraemon: Nobita and the Animal Planet, the second film will land in a comparable space — through a different lens.
What Doraemon: Nobita and the Robot Kingdom is
One imagines the studio pitch meeting involved a whiteboard and the word "robots." Our heroes visit a planet where robots and humans live together, until the Robot Kingdom's Empress tries to reprogram the robots. It's up to Doraemon and Nobita to sort things out, as you might expect.
