Very artistic but not very historically accurate.
The altering of the history of the battle itself is really only a minor issue. The movie is so obviously an art piece more then anything that the historical inaccuracy only slightly bothered me.
In the end, the real flaw of this movie is the lack of character. Everybody in the movie is a cut out prop that exists for the artistic flow of the movie. Even the king who the story is built around has little personality.
Still, it is a decent movie. The sort of 3 star movie that you enjoy watching but won't remember next year.
