Great start about 18 female killers then falters
This title was only used to sell tickets. The movie was actually made in South Korea using a mostly Chinese cast and then picked up by an American distributor. A disciple is tasked with killing an evil master who has a stable of 18 female killers. The highlight is obviously the women as they get to show off their skills in the opening. Things falter a bit in the middle with some unnecessary comedy but then pick up again with the big finale. I have to say the beginning really is the best part of the film.
