From the film clips I saw the emotion was certainly portrayed accurately.
I was newly arrived in the 3rd RECON Battalion, 3rd Marine Division, USMC, just shortly after the fall of Saigon and I loaned a Marine, who had been in Saigon at the time of the fall and is seen in a clip, some money so he could go home on Emergency Leave to be with his Father who was dieing. Every time I see the clip I am transported to that time; no, I don't remember the name of the Marine, I simply handed him $300.00 and he went home.
Politics be damned! Sometimes there is actually a Human Interest Story muddled within the morass of politics and news media!
