This show probably has the most realistic approach to characterisation and dialogue that I have ever seen in a Kdrama before. On the face of it, the plot and characters are quite standard. But the execution is just so nuanced and thoughtful that the show transcends the limitations of the genre. Story: This isn't just a thoughtful romance drama. It's also an excellent meditation on the human condition. You get a real sense of just how lonely it can be out in the modern world. How sometimes individuals are trapped into actions and choices because of their upbringing and personality, and how difficult overcoming that can be. Acting/cast: All of the characters felt authentic and had a real dignity to them. Nothing felt phony or forced. There were no times where I felt that the heavy hand of the writer was guiding the character into some stupid situation or action. All of it was rooted in a reality. The two main leads are fantastic. The chemistry between them is magnetic, exciting, and tragic. Music: Great music. Stylish, sexy, and totally not cheesy. Rewatch Value: It was made in 2007 and yet it still seems very, very cool. A lot of this has to do with the cast and acting but the themes dealt with are also quite timeless. I can see myself rewatching this a few times down the track. Overall I give this a 9. It was a mark short of a 10 because it became a bit dull around the middle for one or two episodes. I wouldn't say it was boring but the show definitely could have done with a shorter episode order. That's a minor quibble, though. All-in-all this is an excellent must watch drama.
