This guy (who, mind you, is not a bad director) already made a movie set in the prostitution world in the previous year, it was not set in ancient japan but it was about a prostitute and a prostitution racket nonetheless. What was the appeal of making ANOTHER MOVIE where the prostitutes play an important part? A whole generation of japanese filmmakers could not imagine ANY OTHER SUBJECT than prostitutes and prostitution because I don't know, they were afraid their manly urges to pay for having sex would be somehow castrated? It gets boring on the longer period, I'll tell you that.
