Đại Dịch Thây Ma

Walk like a zombie, talk (well, maybe a grunt) like a zombie, look like a zombie. Yes, still another unexplained (probably because they can't) plague produces another apocalypse. Two small fenced-in cities survive w/different ways of dealing w/the infected. One looking for a cure; the other just bashing heads. Confusing, disjointed storyline so couldn't get into it. Weirdly, and also unexplained, was an environmental message of maybe after all the destruction humans have done to the planet we don't deserve to be here (hard to disagree w/that point), but most weird is that some humans seem to have become sorta partially a plant & partially a human?? Maybe there's hope for us??
