I thought I'd give this series another try, hoping that the team would do a better job this time. Episode 1 & 2 got me quite excited. I dropped this series after Episode 3. What's wrong with writers these days... Please don't insult your viewer intelligence time and times again. Would any sane person willing to make an appointment with an unknown sadistic serial killer in a desolate place without bringing any kind of weapon or camera to take footage for evidence? Also the said police that tailing them, where were they? Or does the writer thinks that South Korea have such an incompetent police department? Really writer? Really?
