I am writing this review after watching this drama for the third time. And every time I re-watched this drama, I have rated it a little bit higher. Yes, the story isn't exactly original or unpredictable but I have to admit that it is entertaining. I have no idea what the budget for this drama was but they must have spend it a fair bit, especially for the overseas locations. I can't say that the actions were done that well but for a Kdrama, it has one of the biggest gun battle scene I've seen in a drama. Overall, the acting was okay, the story was good but what was exceptional was the OSTs, there were some very memorable ones that stays with you. I would recommend this drama to anyone who is bored with rom-coms or melodramas and want something with a revenge theme and a lot of action.
