I just saw this last night, and I for one was extremely impressed. A friend of mine who had seen it already told me that it was good, but not really anything that special. I think it's one of the best films I've seen recently.
I thought the story and the characters were very interesting. The martial arts scenes were incredible, all though I thought they went a little too far with the wire action at some points (the fight over the water, and the fight in the forest with the blowing leaves, particularly seemed a little ridiculous). The first fight scene is really incredible.
Visually, this movie is absolutely stunning. The cinematography is beautiful, probably some of the best I've ever seen. The sets are amazing in how dreamlike they are.
The acting was excellent for all the major characters. The actor who portrays Broken Sword did an excellent job, as did all the others, but his performance stood out a lot for me.
Overall, I would say this is one of the better movies I have ever seen, and I for one enjoyed it a lot. Highly recomended.
