I don't know what to begin with, I have so many mixed feelings on this drama. I was interested in this drama basically because it's a revenge story -which I really like-. Watching this drama I realized it wasn't just revenge, it was war. The script... Um, it was good. Well written. I didn't really focus much on it, but nothing bugged me about the script and gladly, I don't think there's a good scene that was ruined. So I can say I'm happy with the script. The acting was great. Specially Kim Sang Joong who played Lee Jin Pyo, he was so awesome and gave me the chills with his acting. His character was the most complicating character I've ever seen. A lot of people here were just fabulous with the acting and some were meh. But generally it was great. I didn't hate the main female character, and I'm very pleased with that. Usually the girl is annoying and pisses me off. So I'm very satisfied. And I liked the chemistry. Lee Min Ho deserves at least one good chemistry in his dramas, and Park Min Young was a good choice. I liked a couple of songs in this drama. I didn't 'love' them, I'd say I enjoyed them. But the background music was oh my god amazing. I absolutely loved particular sounds that come on action scenes, it's an instrumental piece called "Sad Run". It excited me so much. The sound tracks in this drama are so awesome. I think I'll download every instrumental piece. This was a great drama. It totally had played with my emotions. There were times were I was really pissed off. and times were I laughed like crazy. and times I was on edge and times I was excited. and times my eyes were teary. And I would even sometime shout at my screen. I like a drama where I'm not numb while watching it. I wish it had more episodes because I really enjoyed it. More bad guys to bring down and more action scenes! I have to say the action scenes were pure awesomeness. They were the heart of this drama. I think this drama deserves a re-watch. And I recommend it to anyone. So goodbye, don't cry, and.. smile! :)) (a song from the drama~)
