If you love action then this is deffo the drama for you. It's fast paced straight from the start and manages to maintain the suspense right until the end. I'll go through the things I liked/disliked about this drama. Liked- I loved the storyline of this drama, you can tell that the plot was well thought out as it flowed nicely, had good pace and you could never tell what was going to happen next. The acting was also great, although I'm still unsure as to what the point of TOP's character was. He was good at acting badass (but maybe that's because he IS a badass), but I didn't understand his character fully, maybe we weren't meant to. But overall a good cast and FINALLY two characters with chemistry. I'm so tired of dramas were the two romantic interests have no chemistry what so ever. This drama isn't even focused to heavily on the romantic genre but it wipes the floor with chemistry! Plus this drama includes one of the sweetest kisses ever (It will melt your heart!) Another thing I liked was the use of special effects and the fight scenes. They were well choreographed and it made this drama visually stunning. Disliked- The music. To be more specific this one song that plays whenever theirs an intense scene which includes this weird buzzer sound. Like the buzzer sound you get in the board game 'operation' when you hit the sides. Obviously not a deal breaker for a good/bad drama but it REALLY bugged me. The camera operators. Seriously, would it have killed them to buy a tripod?? I got motion sickness watching this drama. They need to reign themselves in and stop touching the zoom button when a characters face already covers up the screen. Overall a very good drama and I would recommend if you like action/fight scene and if you're not that fond of cutesy romance dramas with cliche plot lines.
