Vietnam war ended basically in 1973, they use pretty new smartphones and mention Trump as president in the movie, so it's minimum year 2016, are we suppose to believe his daughter is like 43+ years old?

plus there were other pretty stupid situations like the son on mine which doesn't harm him yet kill two other guys and other nonsense

Well yeah, she didn't strike me as being the youngest person in the film or anything like that. What's so unbelievable about her? She looked like she was aging well. I don't see any plothole with her.

she looked she is around 30-35, definitely nowhere close to 43-47, can't find her actual age (Sandy Hương Phạm)

Some folks just age better than others, I guess. You sure are harping on this. You're a very young person, what cha worryin' for?
