Kim Nam Gil makes his return to the small screen after serving in the army, playing the role of 'Han Yi Soo', a tradgey striken young man who is looking for revenge against the seemingly friendly Chairman Jo (played by Lee Jung Gil), who isn't all who he seems to be. Despite its predictablity and safeness in the general plot, with everything else ranging from serviceable to far-fetched, the strength of Shark is the strong acting of Kim Nam Gil and the story of who Chairman Jo was. And of course, the excellent, but short, appearance of Jung In Ki, who played the father of Yi Soo, who is interlinked in more ways than one. The only real faults that I have with the show was its confusing and needlessly overwrought finale. As well as the complete wasteful presence of Ha Seok Jin, who played the Husband of Jo Hae Woo (Son Ye Jin), Oh Joon Young. Lacking character depth with both the teen and adult versions. And on a lasting note, Son Ye Jin was perfectly fine. However, if you replaced her with excellent Kyung Soo Jin, her youngercounter part, you probably have a better show.
