I haven't seen the original drama. This is my first take on the story, and honestly, this movie is one big trailer as you watch you get bits and pieces of the larger storyline. As a viewer, you see the different branches of the storyline being told. But you don't get the full story behind each. It's not a disappointment of a film. It has to some small degree a plot. It has some music that is used both to help the story along or to show the different moods. But it is not a standout soundtrack. Its just something added as another layer of the story. I would say that it is just a too long trailer for the drama. In that respect, it did as it was supposed to. It makes me want to watch the original show and see just exactly what is happening. To me, it did a great job summarizing what exactly is going to happen in a concise snapshot of the drama. My interest in the drama has now made me watch that, but I was hesitant about its length. This movie provided an excellent overview and basic what to look out for a while watching it.
