I'm always entertained by quasi-historical dramas that have an interesting plot coupled with good acting and direction. This fits the bill very nicely. I was very impressed by Chow Yun Fat's performance. His cold cruelty and brutality were a change from his other roles that I've seen over the years. Gong Li was brilliant too as the suffering queen. The acting was good to exceptional throughout.
Apart from that, the convoluted plot is fairly typical of most Chinese historical dramas and I usually like those, this was no exception. The production quality and costumes were truly exceptional. I loved the chrysanthemum covered palace ground, they looked very stunning. There's much to like about this movie.
