But now Kai has returned and he wants to destroy what Oogway has created and remove his legacy like Oogway did with him. While Po has all responsibility to fight against Kai and stop him.

A strong story back up with amazing 3d effects is what you can expect from Kung Fu Panda 3.
As for me this is the best past in the kung fu panda trilogy. The best thing about these trilogy is that it makes you feel relax. full to entertainment.
