This movie is a generational manifesto. A boy that loves a girl; the girl loves a richer boy; the richer boy has no moral values. In this chain, the plot unfolds and the characters' personalities develop to became extremely complex. That's why this is a manifesto for 90-00's generation: they live of contraddictions between their first-world issues (to be in the forgotten middle-low class, to be too rich, to have a father in prison, and so on...) and their desire to dance, to sing, to love, to be free. Some can get past these contraddictions, but others tend to became sociopaths, like Jong-su. Chang-dong Lee creates contrasts with these complexities, playing with beautiful scenarios (the frame with the three characters sitting together and staring at the twilight, seen from their backs, is wonderful) and political references (we see and hear Trump talking about the (in)famous "wall", and Jong-su's house is near the North Korean border, from which we can hear messages of propaganda).
This movie shines a light on young people, their mind and their feeling of inadequacy, and it does that majestically.
