Eh, I enjoyed the original, it wasn't terribly good, but it wasn't all that bad either.
Replacing the Soviets with the Chinese was, in my opinion, a bad idea to start with, but North Koreans? That's just ridiculous.
BTW, this seems to be the exact same thing that happened to Homefront, as it was originally supposed to have Chinese bad guys too.
EDIT: Ah, just noticed that's stated in the article. Should really read the whole thing first.
