I believe that we have been deprived of seeing a master Oogway in his prime. According to the original films, master Oogway was responsible for founding the art of Kung fu. Therefore, it only makes sense to make an animated prequel describing exactly how master Oogway achieved this and how was successful in conveying the art of Kung fu to successive people; for eg, master Shifu.
In general, this movie would just be really fun to watch and I guess that’s what it comes down to.
Thank you for taking the time to consider this petition. The revolution has begun.
