The entire story gets changed as none of the original characters were necessary. This classes it as a re-imagining instead of remake, which is my excuse for accepting this film for the general kickassery within.
Our hero is 12 year old Dre (Jaden Smith) who has to move to China with his mom. He is not at all happy about this change in lifestyle and lashes out in a general teenage sulky way. The story is set up pretty quickly with the new guy falls in love with girl, girl is part of ethnic majority, certain members of said majority take offence, beat him up and then challenge him to a karate tournament. Couldn't be simpler, oh wait that's right. He doesn't know karate. Enter Mr Han (Jackie Chan).
If your a massive Will Smith fan like myself you'll thoroughly enjoy Jaden's performance. While I'm sure he has a future in film making that will vary to his fathers roles, you can kinda feel the same attitude in some of his lines. Some of the looks he has on his face look very familiar. He is an instantly likeable hero and you root for him straight away. Jackie Chan has grown from strength to strength in hollywood and it's great to have him in a mentoring role. He brings the silent wisdom that Pat Morita did and takes it to a darker level. Be on the look out for a nod to a scene in the original karate kid involving chopsticks and a fly.
The best part for me has got to be the choreography. Just because our story revolves around young teenagers does not mean that the fighting doesn't have a really good dose of ouch. These kids pull off moves that Tekken characters would have trouble with.
All in all, I'll be watching this film a good couple more times and I can definitely smell a sequel.
