Perhaps because I understood what they were saying so this is a bit biased.
But it was extremely corny. I mean, think over-acting, exaggeration, you name it, it had it. Obviously, the subtitles don't translate 100%, or the fact that Vietnamese' language is very formal but in most dialogues, I couldn't take it.
That's the thing. Viet people see Korean dramas and try to emulate it but fail. Has anyone seen the boy/girl band resort where they do a high school musical number?
Watching this is the equivalent of watching Days of Our Lives.
