I usually like Korean shows but this one is utterly ridiculous ! The zombies did a good job but the soul-searching plot around it, is long & useless, all the way to sitting around a fire on the roof of the school with pretty & clean blankets (where did they get those ?) One more annoying thing is the constant slapping & kicking each other in Korean shows. What is that supposed to portrait ? Was looking forward to watching it, but what a disappointment !
