It's just plain ridiculous. Having the North Koreans as the enemy is one thing, but simply swapping out their flags and overdubbing the cast in Korean is pretty insulting to all concerned. The film now contains barely a single line of dialogue from the enemy that isn't heard over a reaction shot, establishing montage or coming from a character whose mouth is otherwise obscured. Enemy characters are played by both Korean and Chinese actors, suggesting they can pass for either nationality, but this doesn't bother me as much as the suggestion that the two races are pretty much interchangeable. In the producers' panic to remove all traces of China from the film, they only inject further lapses in logic. Were North Korea ever to mount an attack on a foreign power, the idea that their support would come from Russia rather than China is simply nonsensical. Either as a financial backer, diplomatic go-between or full-on ally, China would definitely be in the mix somehow. Red Dawn barely acknowledges the country even exists.
