I really enjoyed the movie, and the acting overall realism (looking at covid now, and extreme case scenarios, what had already happened - including references to PCR tests, antibodies etc.).
The problem is, I absolutely hated the concept of degrading southeast Asian citizens and trafficked people as the cause of it all. It perpetrates racism rampant in Korea which I do not like. Though the fact that these diseases originated in China us again surprisingly realistic - like contagion - but I felt it made the victims of trafficking the evil.
Also how can the president listen to some random foreigner? Makes no Sense
