This movie is a triumph. Superb writing of an idea conceived by the amazing director Boon Jong-Ho, the shows flows ever so smoothly with interesting characters that movie goers really want to invest their emotions on. What I love about this movie is that it is so strikingly original. It is hard nowadays to watch an original screenplay of a movie, since it can easily veer off to be 'unrealistic' or 'overambitious'. However, I found myself highly entertained throughout the course of the whole movie. What's the best way to watch the movie is to go in as uninformed as possible. Don't even read the stuff online. At best, watch the trailer. And enter the cinema waiting for event after even slowly unfolding. To me, this movie is 'superb' and not just 'good', because of the fact that it left an impression on me as I left the cinema. It made me think about the characters, how their lives would turn out. And also an emotional tug to feel for the characters what they experience. Do not miss this modern-day marvel. A real great break from all elaborate action movies for a solid one.
