Enjoyed the first 3 episodes but then the show did not really have any direction. The characters do not learn from any previous encounters and continue waiting for people to turn before doing something. No consistency in terms of who turns into a "stupid" or "smart" zombie. Too many unnecessary flashbacks. Ample opportunities to kill Gwi-nam but they allow him to keep coming back.
Can see why it would be enjoyable to some people but doesn't really add anything new to the zombie genre.
