At first I was really not expecting the movie to turn out this great. I just liked the unique story and thought I should give it a shot. But this turned out to be a great masterpiece. Everything about this movie is just amazing, the exceptionally brillant acting by all actors especially by the two leads. The groundbreaking storyline, direction at its best, music also at its best, etc. I remember that at start I kept a cup of tea to drink beside my laptop and after two hours realised that it was untouched for the whole duration. That is the intensity and level of involvement & grip of this movie. An absolute masterpiece.
You really need to see this. The Korean entertainment industry is really exceptional, they take such simple and unique concepts and convert them into a concrete masterpiece. This movie will take you on a journey beyond dimensions. The level of creativity and deep thinking that has gone into development of this movie is just phenomenal. I wish one day I also could find that egg.
