Disappointing. I was looking forward to the show so much after watching the trailer (I was really impressed with Train To Busan and had high hopes with Korean zombie films thereafter), but this drama was excruciatingly dragged out and riddled with stupid characters that make you question your own intelligence (MAJOR SPOILERS AHEAD: mystifying the contents of the laptop as the secret to the virus when it can be easily accounted for in a few words: "there is no cure - just kill the host"; dumb kids fighting and talking loudly (as if the zombies can't hear them) in precarious situations and injuring each other unnecessarily instead of retaining their strength; smashing phones as if destroying hardware can stop cloud uploads; being overly concerned about privacy leaks when the entire nation would naturally focus all their attention on a zombie apocalypse; threatening to call the police on a student tying up a teacher (and actually being threatened by that, when the police are busy fighting / getting eaten by zombies and can't even be bothered to save you lol), falling down and calling for help instead of picking yourself up when you are still physically able; characters sacrificing themselves to buy time for other characters that refuse to budge while screaming their lungs out to draw in more zombies. And so much whacking of zombies instead of killing them... as if whacking them will immobilize them at all. Entertaining yes, but nothing struck me particularly. Would not watch again.
