The movies depict a bleak existence for immigrants looking for a better life in a society that thrives on the unequal, sometimes abhorrent treatment of people, esp those who are 'different' and/or those who fall outside a certain socioeconomic bracket. These are not light movies to watch, but if you're concerned about social (in)justice & are in the mood to see a darker side of South Korean society, beyond the rosiness of dramaland, these are both good places to start.
