For Song Joong Ki fans, you shouldn't miss this. And for the others, this movie will leave you the question, "When being skeptic, what would you choose: have faith on what you believe in and take the risks of the consequences OR go with the flow and avoid dealing and gambling with the future risks?" Overall - It was efficiently directed in showing the attitude of people whose doubts were easily controlled by fear. Story - It is not unique in sense BUT the core point had been delivered greatly. The figurative interpretation on how people deal with other people whom are different from them (e.g. rich vs. poor, straight vs. homosexual) had been well presented through the characters of humans versus a mythical creature. Acting/Actor - The casts made an outstanding portrayal of the characters. Each of them had been effectively convincing in their roles. The main leads had been able to substantially showcase the adjustments and development between the characters which have different origins, cultures and behavior. Music - It was the timing, when the music/sound effects were played, made the movie better. Rewatch Value - In times of dealing with the story's moral issue, it is deemed good to rewatch this movie.
