Decided to write a review as a person, who understood the movie completely. (Before, I should say that I watched it not with English subs but with subs in my language that were accurate and appeared much earlier). For me this movie was of one that I call "one-breath movie". Waited for such a long time, as T.O.P fan I wasn't disappointed even a little bit. But I will try to make a review as ordinary viewer. The story, in fact, is not a unique one. And even though this movie is a thriller I wouldn't consider it as a thriller only. Neither it is the story about war between North and South. I've seen it as a story of one ordinary boy, the same age as me and my peers. An ordinary boy, that would love to enjoy his life to the fullest like a normal teenager. Yet, because of circumstances he has to fight and to kill just to protect his sister and to return to normal life. The other story I got attracted to is of Hye In's life (Myung Hoon's classmate). The problem of bullying in school is highly discussed in Asian countries. Yet, the girl did nothing wrong and just wanted to have friends and to achieve her dreams. The story of these two lonely souls is somewhat touching but in the end people only discussing action scenes. Talking about action - Seunghyun did a great job, filming all fighting scenes without the help dubbing actor. If you watch the making of Alumni you can see how hard the filming was, not mentioning that he got a serious injury, yet, continued filming. Maybe I'm too TOP-stanned but this movie was really perfect for me. You won't see love scenes or some sweet moments but I would strictly recommend it, and It really does worth your time. As for me I will rewatch it until I remember all lines by heart.
