In seriousness I liked We Were Soldiers, mainly cos years before it was ever made I read the book written about it by the journalist who was actually there (complete with photo's from his cameraman) and it told the story in great and vivid detail.
It was the first major contact between the Americans and the Vietnamese and crazily the whole war could well have been decided in that battle had it gone a different way... Don't want to go on and spoil it for anyone who hasn't seen it but IMO definitely worth a watch. Although a good while since I saw it, not sure how it's stood against the test of time. Hell of a (true) story though
