The last scean was shocking. Multiple clear errors in a few minutes about korea.
Im sure this director believes that BTS is from north korea or simply have zero knowledge about korea.
Specially when I saw the name of the ship 'kun bae', the genre of movie turned into a comedy. If the director was planning to create a funny moment for korean viewers. It was very successful. XD.
Film makers, if you guys need any advice about korea, just go to any near korea town and ask people on the street, they will give you an advice.
