This drama is about the struggles of the Korean people during the Chinese/Japanese war in Shanghai and a boy that becomes a man capable of protecting the ones he loves and his countrymen. If you don't like violence, then don't watch it. Even the synopsis tells you that Shin Jung Tae becomes the best fighter. I like the story's process of how he grows. I think the writing is really well done. I know a lot of people don't like Kim Hyun Joong as an actor. To that I say "pish posh". The stamina it took him to be Shin Jung Tae through this drama is enough for me. I have never thought he was a bad actor. He may not be the best, but he doesn't suck. Plus he is cute. All of that being said, Kim Sung Oh as Jung Jae Hwa stole the show. His acting is stellar and I could just fall into those eyes. He needs a lead role ASAP. What is with all his supporting and guest roles? Do they not know a good thing when they see it? I also loved Song Jae Rim as Leader Mo and Kim Seo Kyung as Aika (spelling may be wrong). They are both really good actors. Song Jae Rim's little smirky smile is as good as his fighting. The lead actress leave a lot to be desired, but at least Im Soo Hyang as Gaya kicked some butt. I could have cared less about Jin Se Yeon as Ok Ryeon. I didn't like her in Bridal Mask and my thoughts haven't changed after watching this. All of the other actors did well in their roles also. I like the music a lot. If you like action and/or period dramas, then this is definitely one you should watch.
