Well... I decided to watch this drama for two reasons: action, and Bae Suzy acting.
Firstly, I would like to say that I've enjoyed this drama. It had a really nice plot and seemed to head somewhere. In my opinion though, at some point the pace of a story became too fast and it was hard to keep up with the storyline.
Luckily, the cast didn't dissapoint me. The way relationships were created is the best thing about this drama. As I expected, I was amused by Bae Suzy. I also appreciate Lee Seung-Gi acting in this drama.
Sountrack makes another advantage. I actually love it. The two song appearing with the end credits - "Breaking Dawn" and "Open Fire" are my favourites.
Summarising, I've docked my rating due to the not-the-best plot twist.
