This is a great movie involving the dispute between North-South Korea. Hyunbin was able to take the role of Lim Cheolryung perfectly, with the cold stare, dark green suit and swift-like recklessness. Lim Cheolryung's aura was, well, perfect: it supported his back story on how harsh it was for him to endure his most painful betrayal in North Korea's military back then. Lim Cheolryung and Kang Jintae's playful fights always lift the mood up, which is nice. I don't usually fancy action movies, but how swift and calculating Lim Cheolryung's character moved made me like the movie a lot. I fell in love with Hyunbin here, with how passionate he was as Lim Cheolryung. It was a pleasure watching this movie.
