Eighteen years after the first film kicked its way into theaters, the fourth installment of the “Kung Fu Panda” franchise, titled “Kung Fu Panda 4,” was released on March 8. Right from the get-go, “Kung Fu Panda 4” stepped away from its dependency on the star-studded martial arts group the Furious Five. Instead, the film gave its titular protagonist Po (voiced by Jack Black) a new task: hanging up his hat and becoming the spiritual mentor to the next Dragon Warrior.
