The character of Mido (played by Kang-ho Song), Oh Dae-su's captor, serves as a symbol of the oppressive forces that constrain individuals. Mido's character represents the external forces that can imprison and control individuals, while Oh Dae-su represents the internalized desire for freedom and revenge.
Food and drink play a significant role in the film, serving as symbols of comfort, pleasure, and connection. Oh Dae-su's obsession with food, particularly Korean dishes, serves as a nostalgic reminder of his past life and his desire for comfort and familiarity. The film's use of food and drink also highlights the theme of connection and human relationships. Oh Dae-su's interactions with others, particularly his daughter, are often centered around food and drink, emphasizing the importance of shared experiences and emotional connections.
The character of Oh Dae-su is expertly crafted to convey the psychological effects of prolonged captivity and the subsequent desire for revenge. Choi Min-sik's performance brings depth and nuance to the character, conveying the complexity of Oh Dae-su's emotions, from despair and anger to determination and obsession. Oh Dae-su's fixation on revenge becomes an all-consuming force, driving him to sacrifice his own well-being and relationships.
Park Chan-wook's use of cinematic techniques is highly effective in creating a visually stunning and thought-provoking film. The film's use of color, lighting, and composition creates a dreamlike atmosphere, reflecting Oh Dae-su's disjointed and surreal experiences.
The film's editing is also noteworthy, using a non-linear narrative structure to convey the complexity and fragmentation of Oh Dae-su's memories. The use of quick cuts and rapid-fire editing creates a sense of urgency and chaos, mirroring Oh Dae-su's emotional state.
