Believe it or not, I recognize myself in him, especially, the "anticipate, no improvise" bit. Meticulous planning, then stick to the plan. Ha Ha. It is not that easy, you need nerve of steel to do it. So, this movie does strike a chord in me. It is in similar theme as some of the recent releases such as Jonh Wick and another Korean movie where the killer is a woman (so frustrated that I forgot the name of this movie), the hunter becomes the hunted by his deadly equals and emerged as the survivor. This is different to other movies because it was made in a very sleek style, well executed with an even (but deadly) pace, the acting are superb. The weakness lays in the plot with the girlfriend, her role is never clear, except served as a reason for his deadly journey spanning the whole movie. Maybe they leave room for the Killer number 2?
