When people think of 'The Treacherous', they think of eroticism in the movie. However, visual directing should be praised more. Use of water and the color red is very well thought out and appropriate. Costumes and settings show traditional Korea in a sexiest way possible. However, too much focus on sex scene and unnecessary nude scene can downgrade the quality of the movie. It had so much potential to be historical drama but stay being an erotic art film.
