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.

This movie is about nothing but nudity and sex scenes! In the first hour or so there is hardly any dialogue... just a nude scene after another. The only main dailogue is "Take off your cloth." And personally I don't consider this as a dialogue either.I didn't see the love story in this movie... no honest expressions. Just a man who lives a play boy life. I found this movie very boring and I even had to forward many of the sex scenes that I couldn't stand any further!Maybe if this movie had a dialogue, it would have made sense! Maybe if it was shorter! Maybe if there was less sex scenese! Maybe if there was a better (senseful) ending..!

These sheets looked pretty until they fell apart the first time I washed them. How does a sheet fall apart? Well, in this case the raw edges were left exposed in several areas when the hems were put in. The exposed fabric, which is loosely woven to start with, simply unraveled. If you must get these sheets, I suggest you have your sewing machine ready to re-sew all seams and hems before using or washing them.
