Beautifully shot and rather engrossing for some of the cultural aspects and the main character's tribulations as she is foiled in her attempts of pursuing a romantic dream, something apparently forbidden to Geishas. The younger actress playing the part was excellent in her role. Zhang Ziyi and Gong Li also star, and they're excellent too, accompanied sometimes by Watanabe and Michelle Yeoh.
The music sounds authentic most of the time although some of the motifs do sound more Westernised than Oriental, the end credit music for instance. Overall, John Williams did a great job here. We do have the soundtrack and now that I listen to it after watching the movie, I like it more.
Now, this is a very entertaining and romanticised and fictionalised film, so don't expect to find any deep explanation of how a Geisha's life really is. Not only did the director tell about the liberties taken to portray the Geishas but also their main adviser for the movie was an academic who was allowed to wear Geisha garments and follow real ones on their entertainment nights, not 'the first Western Geisha' as she apparently claims. So, this movie brings a smile in the sense that you watch Asian actresses (Chinese rather than Japanese) being taught the things that Geishas do by a Westerner.
The novel on which the script is based was inspired by a real Geisha's information, which proved problematic when the author mentioned her in the acknowledgements section as they have a code of silence. A lawsuit followed which was settled out of court, one point of contention being that in the book, the Geishas are said to 'sell' their virginity to the highest bidder.
To dig deeper, one would have to see a more proper documentary about Geishas or read the autobiography of the above source of info, but this movie won't help a lot to dispel the myth that Geishas equate to prostitutes because of the point of contention mentioned. So that Occidental misunderstanding is bound to perdure, whereas it is also mentioned in the movie that Geishas are artists of some sort, and ideally look for patrons of their arts.
The young main character and Gong Li stole the show for me.
