Same story line
Isn't the story too repetitive in all three? Po tries hard in mastering a powerful skill, faces the villain before mastering the skill, just before getting defeated ... boom ... masters the skill and defeats the villain with it.
This story looked great in very first movie, that was an original piece. Same happened in 2, OK. This third one started great and looked like it will be the best one the series but turned out to be the same again. Will the next movies in series follow this same structure?
