'KUNG FU PANDA 4' IS A SWEET, FUN AND WELL EXECUTED PASSING OF THE TORCH

“Kung Fu Panda 4” finds our trusty, rotund hero Po at a career crossroads and he’s nervous. “Change doesn’t have to be a bad thing,” he is told. “Kung Fu Panda 4” also finds the franchise at an inflection point, but there’s no reason for us to be nervous. DreamWorks knows what it’s doing.

The series’ first new installment in eight years is a reliably funny, sweet and wonderfully realized passing of the torch, with a paw in the past and another into the future — an elegant goodbye and a hello. Many other filmmakers — ahem, Marvel and DC — might learn a thing.

When we meet him, Po — voiced as always by a lively Jack Black — is being asked to give up his dream role as Dragon Warrior and pick a successor. He’s being kicked upstairs to be Spiritual Leader of the Valley of Peace. (This is basically the Peter Principle illustrated in animation.)

Except Po doesn’t want to go into management. He loves smashing skulls and still has that lovable imposter syndrome he’s had since the franchise began. He tries to short-circuit any succession plans, change being too frightening.

A new enemy threatening an existential crisis offers a reprieve — The Chameleon — a wicked, powerful sorceress voiced by Viola Davis — looks like the lizard from the GEICO commercials who spent too much time at Graceland.
