Harvard Film Archive review:
One of Lee's most politically confrontational films, Good Windy Days uses its intertwined narrative of three young men coming of age in 1980s Seoul to cut a pointed cross-section across a society undergoing painful and contradictory transition. Made at almost exactly the same time as the devastating 1980 Gwangju Massacre, Good Windy Days melds black comedy and melodrama to openly critique the rigid class hierarchies that erect cruel obstacles in the wayward paths of Lee's stumbling characters. Although little known in the US, Good Windy Days is celebrated as one of the seminal Korean films of the 1980s and an important first expression of the political urgency and artistic sophistication of the Korean New Wave.
Here (and above) is the opening.
