The film is about the time period in 17th-century. The Joseon reign was a unstable phase of socio-economic in Korea. The aristocracy class ruling the country was only interested in their wealth, they exploited and persecuted the poor. After the appearance of KunDo, he brought confidence and hope for the people here. But then KunDo killed Jo-Yoon’s mother, he began to be very angry and from that is the intense fighting between good and bad.
Precision action sequences sit alongside dazzling period colour, coarse, crazy comedy rides side-saddle with domestic pathos, genre & tone are switched with deft ease, and the pace never lets up. [But] when anything goes, everything seems throwaway.
It's not a classic you'll rave about for days, and at 138 minutes it does go on too long, but for fans of Asian period action, it will certainly serve.
