I just have too many questions... Why wasn't oogway summoned by the chameleon? How did kai survive that explosion from kung fu panda 3? And isn't he supposed to be vengeful at po since he was mad at oogway from the beginning and also the fact that he's a spirit warrior? Why didn't shifu dodge everytime when po touched him like he used to in the previous films? If all the villains are bowing down to po, will the chameleon seek redemption in the spirit realm? Questions aside, I personally find the movie only to be visually appealing. kinda soulless without the five. Overall I'd give this a 4/10
