Curse of the Golden Flower
I just finished watching Curse of the Golden Flower (满城尽带黄金甲) for the second time. The movie is a little bit complex by the plot and requires you to concentrate (or watch the movie for the several times) to get everything out of it but I think it is definitely worth it.
The movie is very rich in form of the costumes and colours and also contains some quite amazing action scenes. I highly recommend this movie. There is something fascinating in this movie, I am not totally sure what that is however.
