1. Gettysburg-I think it really captured the emotions of the time, generals who were friends before the war forced to fight each other, it told of how guilty Lee felt about the deaths of fine men, and how Lee did not want to fight Gettysburg but was pressured to do so by Jefferson Davis because a win in Gettysburg, which is NORTH of Washington would have all but forced the Union to concede defeat.
2.Independence Day-I am a bit of a Sci-Fi nut, this movie really appeals to me, people put aside their differences, fight to preserve the Human Race, and of course the fact that it is America that takes the biggest losses and that it is America that figures out how to defeat them helps.
3. Platoon- I think this captures the emotions of Vietnam well, these soldiers did not want to go, the public did not want them to come back, they had to rely on each other for survival, and it shows the struggle they had to put up with.
4. We Were Soldiers-This movie shows a different aspect of Vietnam, the early years, back when the war was being won, basically before the reporters blew it all to hell, since it was the media that is responsible for the loss in Vietnam, it focuses much more on the families than many other war movies in the past.
5. The Lost Battalion.- This I believe shows that A. Germany greatly underestimated America's fighting ability (some people say that the German soldier in WWII was the best soldier in the world, I say that is BS) and B. showed that Germany was not as evil in WWI as many people think, they valued human life also, they made many offers of surrender to the 308th Infantry Battalion in hopes of saving more lives, plus the commanding officer had little respect for the Generals in charge who did not understand what was going on at the front and often sent thousands of men to certain death.
