Now, solve this: Review: This is without a doubt the worst video I have ever watched.The videos picture could not tracted without jumping lines and wiggling screen it was painful for me to watch.The movie itself was out of focus.They used old black and white movies" indians meet the cavalry " to illustrate the action and pencil drawings of the indian chiefs while they spoke of them. There was one man speaking with a monotone voice.After five minutes it became very boring to watch.The movie was put together very poorly and hard to watch the pictures had very little contrast, and hard listen to.It was so bad I could'nt retain any of infomation,my mind kept wandering off. If you enjoy being bored,and having your ears and eyes assulted by this low grade quality picture this movie is for you. Reviewed by Paul Phillips
