Having met the man, and given the unparalleled opportunity to watch selections from his newest Vietnam effort with him present, I can say that it will be an experience to any who watch it. I was not around for that era yet I was experiencing an odd kind of recognition. Even the forty minutes he screened to the audience was a profound emotional experience. I can’t imagine how incredible the full version is going to be.
Also, the guy himself is just nice as can be. My dad got into a legitimate conversation with him on the blu-ray restoration of Civil War (which he says he regards as his favorite film second to Vietnam), and it was clear he was just as big a nerd as the rest of us.
