Bad Guy is probably one of the most beloved Korean Dramas, so I decided to write a review about why you may not like it...Well the basic reason for that is probably the story.It definitely has a catchy and confusing story but from some point on you keep thinking that it is too exaggerated. There is revenge,love, murder,sadness, passion, obsession,guilt,conceit,conspiracy etc. It's just too much, to that point that it loses its credibility. I had the feeling you can bring out 2 or 3 dramas from the story. As for acting, I think it was well executed.Kim Nam Gil will definietly charm you, but the acting of the Kim Hye Ok and Shim Eun Kyung will also catch your eye, well may also your ear :)The Ost was also good. It suited the drama, but I always had the feeling that it is a little similar to City Hunter's. It is definietly not the same, but you just get the feeling.The cinematography is avarege, it is neither good nor bad, but there were definetly,long and unnecessary scenes.I am a little angry to this drama, because I hoped it would be sentimental and thrilling, but somehow I was lost in the whole plot. Still I watched all 17 episodes, and when you begin, probably you will too...Why? Because you probably like Kim Nam Gil and Kim Jae Wok, not only because they are handsome but also would be interested in their caracters...You will probably be curious about the reason of the revenge. Well I was more curious how much more the plot could be exaggareted. You also will probably like the OST. (no bad comments here) Overall, when I finished the drama there was only one thing in my mind... I really hope they paid the actors well,because it must be very tiresome for them...
