I have never been excited in my kdrama watching the way I had with K2! This drama has great potential and started with an awesome non-stop-action-packed-adrenaline-rush scenes that makes you wonder you are watching a hollywood action movie! But towards the middle when the romance has started and the loose writing is already noticeable, my interest and excitement meter also started to fall down! But it did not stop me from watching further --- only because of my being a huge fan of JIChangWook! Coupled with that , I had decided to lower my expectations so as not to be frustrated further in the end. To my surprised, the ending is not that bad and the writernim has just penned one of the most redeeming and heroic ending scene in kdramaland. Story 8/10 What i like? - The redeeming heroic and sacrificial scenes of Yoojin and Assembyman Jang! This actually wrapped up neatly the somehow loose story of K2. - the non-stop-adrenaline-rush action scenes especially of JCW! What I do not like? - the loose writing, I am actually waiting on the "revenge" plot of Jeha but to my surprised that becames so lame! I dont even know what is Jeha upto? The story turned out to be a bodyguard protecting a damsel in distress plot which is far from its iniital premises! - writernim introducing various and new plots almost every episodes that makes it more obvious that there is no solid plot line! - rushed, overly acted, cheesy romance (although I know romance is needed, but I hope they did not spend so much time sacrificing the most important character dvelopment and story plot) Acting/Cast 9/10 What I like? - JCW as Jeha as I have said JCW just breathe in a new life to the awesome and beautiful character of Jeha. His looks aura and charisma just add up to the total Jeha character! His acting as a soldier, mercenary, a laborer, a bodyguard are just beautifully executed and acted! Jeha is JCW and JCW is Jeha! He owns the character! Although, at some point the character may seems flat, but I guess it is not JCW's fault, it is more of the writing. I must say the character was underdeveloped until the drama ends! Just the same, because of JCW's acting prowess, he just perfectly executed enough to satisfy us until the finale. - SYA as Yoojin, the QUEEN OF DRAMA! She is the ultimate heroine/villainess rolled in one! She is brilliant, smart and intelligent! As Yoojin, she is evil but also a victim! She can make everyone her pawn. She can kill a person just by lifting her fingers. But she never felt loved eversince even by her father! Yes, people around her are loyal to her but only to a certain extent! She is a person in need of love and affection! But she also need to be punished for her wrong doings which are a lot. The writer neatly give the punishmen she deserves at the end which is satisfying, redeeming and heroic! Others support also did their job well! All the actors and characters lived up to the expectations in terms of acting. Music ( 8/10) - the OST's are just adequate to make the emotions more moving. I dont like though the chanting background music. Rewatch Value (7/10) - if there are scenes I would like to rewatch it would all be the scenes with SYA and JCW! Man, they are explosive, romantic or not, they are just palpable! Overall, even if this show has numerous flaws, I would still want to recommend this to fans who loves action and JCW!!!
