I watched a number of reviews, from multiple perspectives, and my take-away is that the original animated feature is Magic in a Genie Bottle concerning cultural influences and "nods", and the live-action Disney budget Kung-Fu film was an imitation of the theatrical medium that are the original Bruce Lee movies. I would not equate this martial arts fantasy tale as anything other than a modern interpretation of an ancient poem about a female warrior. But it's not Mulan to me... that's a musical animated feature with silly jokes and beautiful landscapes and a great score.
So no, we won't pay extra for it, and I highly doubt we will ever get around to watching it. If I want to watch a Kung Fu film, I'll go watch a Bruce Lee movie LOL
