I was like you guys when I first saw the trailer for The Karate Kid 2010. I turned to my son and said it's going to suck because all remakes do, and we sat down and watched the original the following weekend.
I quickly apologized for making him sit through that and promised him that I would take him to see the new movie for being such a sport. I'm glad I did. I wish all remakes could be like this one. It's not Oscar worthy but it was a good damn movie.
There is one scene in the new movie that made me glad I watched the original with my son though. It was word for word with the original but the lines where delivered in Chinese. I'm not going to spoil it but my son turned to me and uttered the English equivalent. What an awesome moment to share with my son.
