Despite the recurring story blueprint of fat Panda vs menacing villain and kung fu chit-chat, Kung Fu Panda 3 works for the same reason, the first two did. The damn good humour.
The third part is easily the most hilarious of the lot, despite some hiccups in the story (unconvincing 'Spirit Realm' afterlife concept). Considering the first two films are a laugh-fest, writers Jonathan Aibel & Glenn Berger border on the genius here. Genuine ROFL moments await you, no kidding. More so, if you are a Kung Fu Panda fan already, largely for the deja vu moments.
Directors Jennifer Yuh Nelson & Alessandro Carloni add numerous little touches to gorgeous animation, best seen on 3D. Jack Black showcases again why he is a steal of a dubbing cast as Po, as are the others. Easily the funniest animation movie (and trilogy) on kung fu that you will see in a long time.
