An interesting and disturbing film set in Seoul, or other big South Korean city, illustrating the increasingly larger gap between the haves and the have-nots, where a poor family desperate for a decent income but whose young adult kids are well educated, cons it’s way into a very rich but rather naive family’s house. Some of the plot lines were hard to rationalize, especially towards the end, when the situation becomes, to put it mildly, rather out of hand for both families. I would not recommend this movie for families with kids younger than about mid to late teens. It has some extremely graphic violence towards the end which is hard to deal with for some people, including me. Technically, the film was brilliant in every way. It is subtitled, so you have to watch and concentrate on every frame.
