Assured story telling from a director whose subsequent output has been spotty at best. One of the few, if not the only, films to present that moral quagmire of the times both on the domestic front and the battlefield. It was controversial for its depictions of the Viet Cong and post war Saigon, but the controvesrsy likely was a reflection of America's tortured conscience about the period. The film is probably worth a look again given the events of contempory times.
The scene of the surviving friends singing "God Bless America" at the end is quite stirring.
