I've finally finished watching this one, and although I've managed to watch the whole thing in just a few days I still want to use the term "finally" coz for me it felt a bit long. As every one knows this is a drama-remake of a very popular and high grossing Korean Movie of the same title, of course the story is a whole lot different than the original movie's of course because we're talking about a 20-episodes-long drama compared to a 2-hour-movie. This Drama had potential, the story's layout is quite interesting by most standards, bit of a "Mr & Mr's Smith" with all the spy Vs Spy missions and the romantic line involved causing the dilemma. But despite all that it would be fair to say that this drama didn't make the utmost use of all these weapons it had at hand, and sent most of them down the drain. The first few episodes (to be specific until they got assigned to the NIS) weren't interesting enough to keep me hooked, but as an old K-Drama fan I know how most Korean dramas are a bit hard to warm up to at the beginning. To be honest with you, one of the main reasons why I couldn't get myself to warm up to the show quickly was my annoyance at the female lead's choice. I don't want to keep talking about how old she looks comparing to Joo Won (he should just call her "Noona" lol)coz I guess many people must have already killed this issue discussing, but also her acting wasn't that great and to add insult to injury the character she played had so many nasty points to it, in a nutshell it was mostly hard to sympathize with anything she said or did. The romance developed quite fast, too fast that it made the watcher go all anticipating as to just how much we'll be getting busy through out the rest of the drama, and no argue we REALLY did get busy!! but not with the romantic or comedy plot, but rather with the plot that the writer just simply sucked at; "The Spy Game" If this drama was a spoof for spy movies it would have made sense, I mean why the hell did nothing those NIS agents did that made any sense whatsoever. Let's say that this is a Rom-Com in the first place and that it shouldn't be judged on the whole spy line. OK even if I manage to agree with that, let's be honest, the whole idea behind the drama is that they are both agents who fall in love but have to keep hiding their identities from each other, so ultimately the two lines; romance and spy, have to end up getting tangled. And this is where it all felt so frustrating. I enjoyed the first half of the drama, to say before the Baddies made their first appearance. I enjoyed it because it was full of cuteness and funny silliness not the type that frustrates you though. At the beginning I could to a certain extent feel empathy towards Seo-Won's character and even sometimes feel bad for her, but later the more the plot developed and all cards got revealed, her insistence on not sharing everything with him and acting all mighty made me just hate her and wish he would just do the same. I know I said the plot evolving around the NIS' missions and spy work should not be my main point in reviewing this drama but I still can't hold back some of my comments concerning that one. The whole baddie guys' revenge was stupid and badly written so I on purpose tried my best to ignore it so even if some parts didn't make any sense i wouldn't linger and wonder a lot. The NIS itself and all of it's agents felt like a bunch of dummies playing 007 and not even managing to make it close. The mere idea that they get to cover such missions after only one year of training (which I bet involved basically drinking and dancing and gambling classes) felt so unbelievable. But I must congratulate the writer on one thing, the agents did seem like a bunch of rookies who just didn't have any idea what they were supposed to be doing. Starting with the supposedly strongest and most experienced of them all; Do-Ha with all his spilling and tripping and pink-panther-sneaking during a mission! to Sun-Mi who fires a gun at headquarters by mistake, and instead of feeling any remorse just goes butterfly on her crush covering her!! (she should have been told to hand her resignation just there) To Seo-Won who can't even drive properly but can still snowboard and use a sniper even while shaking and sobbing!!! Even the baddies most of the time seemed they just had no idea what they were doing, going around in circles not even reaching an agreement on the meaning of taking revenge. Let all these plot-holes aside and concentrate on the romantic story line and you might enjoy the drama more (like I can say I managed to). Putting the action aside and concentrating on the characters and their relations, you will still notice some irritating flaws with the characters: (as I previously mentioned) Seo-Won with her meaningless wish that Gil-Ro believes her although she does absolutely nothing to gain his trust but rather act all the more suspicious. Do-Ha, who says that he can even do bad things if it's for the good of his country but later on with the drama ends up conniving a crime that of course has nothing to do with anyone's good. Sun-Mi, was by far the most childish character and should have never been an agent in the first place. So although I really liked her tomboyish character at the beginning I ended up hating her bad-loser clinging puppy personality. The big guys (Won-Suk and Director Oh) with all their "if anyone finds about what we did we will be dead" bullshi* (Needless to say) the Bad guys!!!!!!!!!!!! GO TO HELL!!! So the writer nearly sucked badly at the spy parts which covered most of the drama, but somehow I still managed to enjoy this one, but only for the laughs. So the serious emotional parts I watched with one eye closed, and the action spy parts I watched looking elsewhere. lol So why did I give it 7 and not less? it's because I loved the silly/funny/cute comedy scenes a lot, and also found some heartwarming plots to cling to (like Gil-Ro and father conflict). one last advice, if you're going to watch this one through, better skip seo-won's parents' scenes, these are simply a waste of time and energy.
