one of the best korean drama i've ever watch...i dont know why the rating wasn't that high in korea...i do stop after 4 series, but when i start to watch again, i just cant stop anymore! the plot was perfect, action and comedy combine from the 1st until the end...some other dramas tend to loose their comedy side halfway but this...i can stilll laugh even when things suppose to be serious. i hesitate to watch it at first because theres 20 series, 1 hour each, Oh My God....but...at the end i feel like why theres ONLY 20? i think the ending a little bit to rush but the storyline still strong and smooth though. they capture all the conflict (politics, dirty money, etc) really really well, i can feel the reality in it. cast : all of them have a strong presence...my favorite is ahjumma of course, the rest still great. i really love ji chang wook who jumping around at night...even the supporting cast made a strong impression for the drama. music : i dont usually give credits to music, yah because korean is like an alien words for me but...this drama made a very wise decision when they use Michael Learn To Rock "eternal love" as one of their soundtrack, because me, as a stranger to korean words, i can read English and i can feel the drama more when i understand the words in the song. this kind of dramas is worth watch worldwide, and one of their strong point is the soundtrack. and, the most important thing is they put the right song in the right scene. i will watch this again at some point....but considering theres 20 series to watch...maybe later. i hope this will encourage you all to watch this gem.
