As the second part of the "Vengeance Trilogy", "Old Boy" still continues the theme of revenge for the loved one in the previous film, but the director has made a great change in the processing of the image. The twists and turns of the plot and the stimulation of conflict, coupled with a large number of camera motion paragraphs and character actions, coupled with a high-pitched symphony, add more entertainment elements than the previous work "I Want Revenge". This film is adapted from a Japanese manga of the same name. However, the film expressed through real images not only challenges the audience's psychological limits visually but also morally.
The film has a profound description of life, ethics, love and psychology, giving the audience deep and heavy thinking.
