I didn't see the manga or the Japanese version. I just found it by luck. And, let's be honest, most of us, including me, watched this drama because Dongho and Hoon are acting in it. However, i wasn't disappointing at all. BTW*, i know that some watched it for poster or because they've seen the Manga...so that is why i wrote MOST...not ALL...shall we get to the main point now? Story (8/10): The story is not new. Kang Yu (played by Dongho) learnt a rare technique in boxing and started to defend himself on the streets. The feeling of heartbeat in his chest has made him feel alive again, so he decided to remain on the streets and fight. The whole drama seems very slow, and i think it is done on purpose, to get you in the thinking mood of the hero. He thinks a lot about everything, and that made me understand him even more. There wasn't much told about the hero's, or any of the characters', background because they wanted u to be wondering about the hero. To try to figure out his psychological mind. To actually think about the drama and figure out why all of this is done like this or that... Acting (7/10): The cast were all great. They've done their job skillfully. They didn't exaggerate or underestimate their roles. Dongho couldn't be like the Korean Kristen Steward because the American Kristen Steward didn't play a boxer in the korean streets. BTW, I don't think that the American Kristen Steward can actually pull of a scared/ serious face like Dongho. Music (9/10): As the fighting scenes are really exciting and pulling, u might not be able to listen to the background soundtrack, but the Music is awesomly enjoable and fits greatly in the drama.. Rewatch value (8/10) Overall, i recommended for thinking people, who are willing to actually think about the drama and don't just watch for entertainment. If u r not willing to think- and am not saying it's a bad thing and am not against it or anything, am just saving your time- please drop this drama BTW* : By The Way
