First of all, great acting on the Kim Young-kwang part, since I have only seen him act in soapy K-drama. This was a proper psycho performance. Great acting, amazing cinematography, the script and storytelling may be confusing at some instances, but over all, it is a great show. Someone wrote that it was better if they made it into a movie and I think I can agree with that. I would like to see season 2 with totally new characters and a better story. Also, I was not so surprised that people thought the cops were stupid, I think that's usual in Korean movies, they often portray cops as incompetent.
