[EX Q]: All the elements of a great movie. What can I say, I love to study the elements of war, and I enjoy a good love story along the way. This movie was a great introduction to the role airplanes had in the first World War. Featuring the story of the Lafayette Escadrille, and the role Americans had in the early aerial engagements. The story also allows those who have little knowledge about early technology to understand that it was very rudimentary. (Using hammers to clear your machine gun comes to mind.) The soundtrack was very well done, and the needed animation(?) was excellent as well. I highly recommend this movie.
