The South Koreans have jumped ahead of most of the foreign film makers around the world for one reason.... the South Koreans STUDY and analyze American cinema (at least the good cinema) very closely and try to emulate it. This made them jump way ahead of most of the other nations in Asia and ahead of most of the Nations in Europe. (have you tried to watch a French or Swedish movie recently? zzzzzzzzzzzzzzz)

Anyways, this looks pretty cool, and zombie apocalypse movies are kinda the rage now with our current pandemic LOL....
