This a very well done film. The acting was great, especially Yoon Kye Sang. This was the first time I saw him in this type of role and he was simply brilliant since he beautifully conveys all his emotions without uttering a word. Still, I felt something was lacking. I didn't like the main actress, at all. When her character appeared was when the movie started to drag on and on for me and I practically lost all interest in it. It did start to pick up a little in the last 20-30 minutes of it, where we are shown a very thrilling scene. I won't be watching it again since I find the film is forgettable and I didn't enjoy it.
