Well , probably a lot of people will jump on my head for this review but here it goes . Acting 9/10 ... The actors were really good . some of them were credible enough but some of the actors that were supposed to be realistic .. barely were . Still 9/10 since the main actors managed to cover up the acting of the others Music was really nice , during the fights and op / end .. good choice and it made it enjoyable .. I have been listening to the ost since the 1st episode Here comes the story .. 1st episode came with a huge potential it would have gotten a 10 if it kept going like that .. but as things unfolded I was more and more disappointed .. - many plot holes - many unrealistic stuff happened .. like : - fights - the guns - some of the characters were portrayed as very stupid even though here we talk about world class mafia right ? korea s finest mafia .. cops are included in this also . Even with all this bad things .. the story was enjoyable , the romance was nice and pleasant to watch Last episode was what saved it for me ... This drama is defiantly worth a watch ! - but keep in mind .. if you saw good action movies like the man from nowhere .. i saw the devil .. or even black and white where you could call the action action this will seem like child play . if you want to watch it for romance + action boy save girls that kinda stuff its really good
