The concept of this film was unique and interesting. The handling of colour grading in this film helps us to understand the film clearly. Though this film makes us to collapse in middle portions but we can get a clear understanding by watching till end where a suspense waits. The non linear editting which makes collapse little bit where I felt watching sir DIRECTOR Christopher Nolan films. The acting of the two main male actors was really excellent especially when love feeling scenes.
At climax we feel some undefined feelings in our heart where the film wins.One of the Excellent movie from South Korea.
