From the very first scene, the cinematography is very beautiful. It's one of those movies where you'll be wondering "what did I just watch?". With top-notch acting, the cast is just perfect. Kim Nam Gil and Sol Kyung Gu as usual delivered a spectacular performance. I am a big fan of Kim Nam Gil and it's my first time seeing him as a villain and I have to say it he pulled it perfectly. In spite of your best efforts, you will never be able to predict the twist the director created. There's nothing better than watching a good thriller movie, and this just hits the spot.
Watch it, it's worth it.
