This is total rubbish! I don't think I've watched such a bad show before. It is through and through ridiculous. Totally unbelievable, terrible dialogues, repetitive, lots of plot holes and bad acting by the majority of the cast. Only reason I kept watching is Kim Jae Wook - 10 out of 10 stars for his portrayal of a mad serial killer. If you just watch for him don't start watching before episode 8 and don't hesitate to fast forward just to see his scenes. You won't miss anything! I don't get the higher ratings for this show or why it got more seasons.
