This is an entertaining piece of modern-day fiction that features great CGI, comedy, and drama. The acting is decent. Tae-hyun Ja plays the protagonist and provides the core to the story. Jung-woo Ha as Captain Kangrim, leader of the guardians entrusted to protect and defend Tae-hyun's character is the real hero. He is charismatic, and his talent is not wasted in the movie. Ji-hun Ju's role as the sarcastic Haewonmek is not as effective. While his sarcasm is supposed to provide the humorous foil to Jung-woo Ha's straight character, it makes him come as cold and callous. Hyang-gi Kim is the most sympathetic of characters, and chews every scenery she is in. She portrays her character with the most depth, even if she is not given too much to do. What makes the story interesting is how the life of the protagonist is unfolded as he progresses through each trial, and every detail uncovered is unexpected. This is the strength of Korean storytelling. They come up with many unexpected twists. The fantasy creatures look decent, but it is no Lord of the Rings, and the characters portraying deities look farcical. But probably the movie does not intend to take itself so seriously but it interestingly discusses issues such as life choices, and handles the drama extremely well. There are spectacular fights, and chases reminiscent of The Matrix: with the coat and all but in the end, the movie will leave you satisfied and feel good. I wonder if they have a sequel in the plan.
