This is a very good drama of its genre. If you are a suspense/thriller/revenge drama fan, then you will certainly like this one. This drama deals with the normal kdrama cliches of lost children, parents being killed and then sons taking revenge, but for some reason I found it interesting and addicting. There is a love story but it starts off in the begining and everyone stays firm with their emotions, the love triangle (yes ofcourse there is one here too) is there but its not too dominating and annoying. The acting is very good, especially UTW is simply great as always. The leading lady was good too, but for some reason the sad watery eyed look doesnt appeal to me too much, so I found her miserable state a bit annoying (although it was appropriate according to the script, so I guess its not her fault) I would have been happier if she was shown a bit happy at times too, she had the same look through out. I like the second lead girl much better. Now the negative point was that the drama was really really slow moving. I dont know why they have 24 episodes of a good drama, when it can be a great drama at 16.
