Well sweeties, The Karate Kid (2010) is called The Kung Fu Kid everywhere else except in America. I guess they're tagging on the name's popularity.
Anyway the first one was a classic. The remake was as expected flashier and modernized. I did enjoy the fights a lot more in Kung Fu Kid, also Jackie Chan's character, Mr. Han reminded me so much of my father, down to the awesome mustache. XD
I say it's close call, but I want to say the original was better for, the kids in the 2010 one were way too young for their roles, and maybe it's just me sounding old, but I didn't care for the music in the 2010 one. I did enjoy it though...mostly because Jackie Chan was in it. XD Also the move Dre used instead of the Crane Kick was awesome.
