it look like the movie do not cause much money and but it do cause the director a lot of think to put his thought into this comedy . the movie express a nationalism idea in the director own opinion represent unite with the north and go against the foreigner . the comic part be mostly from the portrayal of south and north ( the north officer always stand on the left and north korean soldier arrogance . ) i love the end very much and when admiral lee 13 ship have to face the 300 ship from japan ( a real battle in history which koreans won ) and he motivate his sailor represent a we be united and there nothing can stop u . which be the idea the director want to tell his country men . korea be a small country compare to any potential opponent and it have to be unite .
