Funny to hear all the commentary and reviews on this movie. I have yet to see it but expect that I will.
As such, it is entertainment. If one wanted accuracy and fact they would watch a documentary...maybe.
I was screening some documentaries from US involvement in Vietnam last evening. Needless to say, even these had a certain flair to them, typical government produced quasi propaganda that at times seemed quite doubtful even though they were presenting "fact". Interesting to note that a great deal of the included information has since been disputed, disproven or altogether dismissed in the years since files have become unclassified.
Sit back, relax and enjoy the movie.
