The only thing I knew about this film was that it had lesbian content, and it was a really nice ride to watch the whole story with its twists and turns, that go much beyond that.
I'd only say that it is a con-story set in Korean during the Japanese occupation and that you should be prepared for adult content, but that this film is much more than that. Indeed, it has the right mix of mistery, humor, erotism and romance, all with a gallery of weird characters and breath-taking sets, costumes and photography.
My only criticism would go to the explicit sex scenes, beautifully staged and filmed, but that feel a bit exploitative toward the actresses, especially because one of the characters is precisely trying to escape an exploitation situation... In my opinion, the film would be equally interesting without such explicity.
But all in all, it's an outstanding film!
