I loved it ! The storyline is simple and easy to understand. It does not have any draggy or unnecessary scenes. The movie is fast paced so you are constantly alert while watching. Packed with actions that will blow your mind. Lee Min-ki is brilliant in here. His co-star, Kang Hye-won was also good. Kim In-kwon provided the comic relief and he certainly delivered. Right from the start, the movie grabbed my full attention and I almost didn't blink throughout the whole story. Go watch it and you'll know :)
