For a film about a masked wrestler, there is surprisingly little cheesiness to this film. We follow a downtrodden banker as he invests his self esteem in the sport, and first see it treated in a very realistic, everyday way, without dramatic music or camera angles and are allowed to see the inherent ridiculousness of it. As the film builds up, and becomes more stylized, it hasn't made a grand statement about wrestling, but allows it to be seen as reality.
With this, the fight sequences become one aspect, while the real heart of the movie are the Mr. Bean like physical comedy bits where the main character tries to get respect in his everyday life. While a few key scenes take place in the ring, the best bits are in the office, on the street or in the park. In tone, pacing and style of humor, I'd call this film the Office Space of Korean cinema.
