The film is composed of high caliber casts (though I only know Park Shin Hye hehe) and I believe they did their roles very well, but I would like to say that the story line itself could be original at some parts, like the survival of newfound neighbors finding their way into another, but it is highly predictable and clicheist. So many deus ex machina, and some actions of the characters were quite illogical, like the guy who hid his zombified wife in his house and that scene in itself is lackluster. But I highly praise the production team for all the satisfying visual effects and design, and the opening theme is quite good and appropriate in showing the grim reality and highly detailed transformation of a human into an infected.
