A surprisingly good warmovie.
It has realistic battle scenes, competent acting plus it shows the Vietnam war from the medics' and doctors' point of view. The romance was believable and Cheryl Ladd was always a decent actress (and good-looking).
Battle scene highlights: the NVA assault on a USMC firebase. Those Marines' bloodlust was on a par with the NVA's!
I don't like chicks' movies, or *romantic* movies. I do agree however, that nearly all warmovies need a healthy dose of realistic romance. 'Purple Hearts' provides us with just that.
