>>98133790Spent too much time on the other pandas, underdeveloped the villain. By the way, did Tai Lung escape? We know Kai brought him (in trinket form) back to the mortal realm, but it's never stated if he gets loose or is just a trinket for he events of the entire film.
Also the ending felt rushed. Po shouldn't have mastered chi, rather he learned some basic use thereof (like healing) to break the jade curse put on the masters fighting him and then they have a big teamup battle against Kai.
