Query: Did Not Like This -

I did not like this documentary - far, far too heavy on efforts to hype the dialogue and emotions, not enough on actually touring the country and seeing eg. Pleiku, DaNang, Hue, Nha Trang, and Saigon before and after. I was, however, taken aback at the very beginning - seeing a modern Boeing 737 utilized by a Vietnamese airline.
