The movie is fine as long as you know this is fiction, not history. There are some items in it which are historically relevant. The costumes are OK. But Greek fire was invented long before 1357 and would have been known to both the English and French of the day. And I am not sure how a 20th century archaeologist would have recreated it since the formula appears to have been lost after the Middle Ages. And I was surprised that a French lady of noble birth would have spoken English since many of the "English" still spoke French and not English as their native tongue. But, in spite of its shortcomings, it was still an interesting movie.
