To begin with, while in the hell the movie had to be called The Karate Kid, if what the boy learns (in this version) is Kung Fu? I even liked the movie. Yes, it is a remake/adaptation of the original one. Now the kid doesn't learn Karate, but Kung Fu. Quite a good movie. One of those you would expect to watch on that afternoon movie session on TV (yes, not on the movies/cinema). Worth watching, not worth buying the DVD/BlueRay (unless you have serious problems like movie addiction).
Not much to say about this one. I still like the original movie better.
