A very brilliant movie.

The storyline is perfectly done, it really build up our emotion to see the friendship of those 4 friends. The story is not lacking nor exaggerated. It also have unpredictable storyline which you cannot expect it.
The story have combination of action, friendship and a bit of suspense.

The acting also are superb. Jang Dong Gun played his roles well in this movie, one of his best performance.
Oh Young Su as a gangster & loyal friend also makes me cry for him.

What I like from this movie??

-the flow of the story
-the two main characters,(Jong Suk & Dong Su)
-the climax which brilliantly done.
