I am so overwhelmed by this drama that my review probably won't do justice to this masterpiece. But I'll try anyway because it seems that many people rated this drama only according to its end. Believe me when I say that this is one of those dramas that is completely underrated. The story is a common plot among all those revenge dramas out there. Han Yi Soo takes on a new identity after his father was murdered. After years he comes back to Korea with a fully prepared plan in his mind. In order to get the one responsible for his past misery he is determined to use that one's granddaughter Jo Hae Woo, his past first love from his teenage days. What makes this drama so perfect in my eyes is that every detail harmonizes with the other entirely. The story, the twists, the actors, the music, the cinematography. Although the basic plot is not an unusual one, it still keeps you chained to your seat. The way the scenes are merging and continuing so smoothly makes you more curious with each passing minute. But the story itself wouldn't work without those remarkable actors who put so much life in their characters. At this point the first ones who are to be mentioned are Yun Joon Suk and Kyung Soo Jin who portrayed the young versions of both leads. Without them it would have only been half a joy watching this drama. Their chemistry was overwhelming and laid a great foundation for their adult co-actors (Kim Nam Gil & Son Ye Jin) who did an equally amazing job in showing that deep special bond their characters shared from the first minute they'd met. All those moments/scenes where they were together was in a striking contrast to the rest of the story and kinda felt like floating in the air. Their encounters always left a deep impression on me. What strikes me most is Kim Nam Gil. I've never seen anything with him before, therefore I had no idea what I was getting myself into. But after watching this drama I'm completely convinced by his talent. Not many actors are capable of showing sparse facial expressions and still manage to deliver everything the viewer needs to feel the character's pain, suffering, inner turmoil and determination, or whatever he's feeling. The most beautiful part of Shark (next to those wonderful tragically romantic moments of the leads) is its unique, outstanding OST. All those well placed songs just complemented this already brilliant drama. Believe me if you've ever contemplated to watch this, don't hesitate any longer. Just start it. Like I mentioned at the beginning many people were not satisfied or disappointed with the end. In my opinion it was the most fitting finish I've ever seen in a k-drama. If you pay enough attention right from the first moment, you would see it coming. Throughout the whole story are so many small details that point towards it - like a red thread. You'll see that any other ending wouldn't cope with the rest of the story as well as the actual one did. Not at all. I for one have fallen in love with this gem. I hope you guys will enjoy this ride as well.
