It's one of a masterpiece. The plot and the main lead actors acting is the strength of the drama. The main male lead actor, ji chung wook just nailed it, his acting was at It's peak! One of his look with bloodshed was terrifying. And fight scenes are awsome. There is a fight scene were thr other gang attack 2nd lead's gang, then the two main lead actors fights back as their last fight..it was hell like fight. Brotherhood genre is the mai strength to the plot. But there is a scene which felt awkward, which is the main actress and 2nd lead's kiss scene. It felt like awkward, also the main lead's (ji chung wook) and other mafia girl's kiss scene. They were essential for the drama, they can't exclude it. But it really felt awkward watching it. Because they have already married to eachother(ji chung wook and main actress). In the end It's emotional. But i think that's better. It's like a happy ending kind of a feel.. Really that's the better end for the main leads.
