If you loved Doraemon: Nobita's Dorabian Nights, try Doraemon: Nobita and the Kingdom of Clouds
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's Dorabian Nights

Doraemon: Nobita and the Kingdom of Clouds
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's Dorabian Nights, the second film will land in a comparable space — through a different lens.
What Doraemon: Nobita and the Kingdom of Clouds is
Here's a film for the kid who's ever wondered if there's more to cloud formations than cumulus and nimbus. Nobita builds a utopian kingdom high in the sky, only to discover warring factions already in residence. It might inspire some thoughts about the real world's environmental issues, or it might just be a pleasant distraction.
