I watched part of an episode on Decades a while ago and it was jaw-dropping what they did in the series. In the episode Caine was trying to protect a Chinese family. Making Carradine a Chinese character was obvious yellowface but watching him in a scene with Chinese American actors pretending to be one of them was mind blowing. Whatever plot there was served only to set up the fight scenes but Carradine was truly awful at martial arts. All of his moves were sloppy, especially his kicks. If you get a chance to watch a little of the old series do so just to see how wrong it is.
A reboot of the series on CW is going to be like the reboot of Hawaii Five-0. Outside of the names it will be nothing like the original series and it won't matter.
