If you loved Up, try Monsters, Inc.
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 Pete Docter, and they both carry the tender mood tag, and they sit in Animation / Comedy / Family territory. If that's the register that drew you to Up, the second film will land in a comparable space — through a different lens.

What Monsters, Inc. is
Here's a film that asks, what if monsters had to scare kids for a living? Monstropolis' top scarer, James P. "Sulley" Sullivan, and his pal Mike Wazowski find their world upended when a human child breaches the monster realm. It's up to them to return "Boo" home without causing a panic, which seems like a metaphor for parenting.
