The 3/5 is for good directing, good action scenes and pretty enjoyable at times but where it gets weak for me is the story and most disappointingly, the choice of bringing back the og villains and ruining them. I mean COME ON watching lord shen being an absolute menace and suddenly looking do peaceful and bowing in front of Po ? Seriously ???. If you wanna bring back those amazing characters then also show some respect for their characteristics, not just bring them back for creating fake hype. 

Overall, not so disappointing as I thought it woulf be but definitely disappointing in the that I discussed above. Enjoyable watch with good music and animation.
