Personally I think this series isn't something everyone would love to watch. When it comes to making kdrama with psychic thriller concept the creators need to be really careful with what they are putting up on the screen. Some scene portraited in the series can be extremely sensitive to some people. Since we don't get to see much kdrama with such intensive act shown by the actors, this series definitely paved a new path in the kdrama industry. The cinematography and so was the story line as it showed diversity by dopting many things from the pop culture and applying them creatively. And the last thing I would want to say is that if you really want to watch the series then watch it full, don't leave in mid way or skip scenes.
