My first Action drama ever (huge romcom fan), I took a chance due to my new found obsession with Jang Hyuk... Story: Fast paced and unpredictable, revenged themed, with an angsty love-line thrown in. The ending is WTF! Acting/Cast: This my first Lee Byung Hun led drama. Well what an introduction it was! Not only is he good looking but he is an amazing actor that was made for this role. He had such an amazing chemistry with Kim Tae Hee. Although I really like her, I think Kim So Yeon kind of stole the show. All of the rest of the lead and supporting actors were perfect. They really casted this one well! Just be prepared to see some characters come and go... Music: Actually a really good mix that fit when the mood changed (romantic to action scenes). Rewatch: I loved the entire cast and the plot was exciting so I definitely will watch this one again but not for a bit case the ending left a bitter taste. Final Thoughts: I dare anyone who hasnt seen this to give it a try if they want an exciting 20 hour ride!
