I agree about the title/martial arts snafu- its a typical Hollywood goof that simply didn't need to happen.
It insults the traditions of the martial art depicted by giving it a false name in the movie- surely, Kung-Fu has enough recognition to warrant using its actual identity in the title.
It insults the martial art in the title because it isn't being used to depict itself, despite its own incredible traditions.
Then there is the matter of using the cultures of 2 very different nations interchangeably, 2 nations that don't have a history of friendship... Its like doing a WW2 movie with all the Nazis having French names & accents while invading and occupying Germany.
If this was a conversation in an old Kung Fu movie, about now, you'd have the students squaring off in the alley to shouts of "You have insulted our master!!!"
It also makes me think that the next iteration of The Karate Kid- be it TV series or yet another movie reboot- will feature an even more cinematic martial arts style, like Capoeira...and will still be called The Karate Kid.
Still, its kind of nice to see Jackie Chan return to his roots in a sense- he started off in Chinese theater (stage, not movies), which is where he started to learn and develop his more cinematic style of martial arts.
