Bong Joon Ho’s movie Parasite, which reached US theaters last month after its initial South Korean release in May, has been a massive hit among critics and audiences alike. After its Palme d’Or–winning première at Cannes, it sold over ten million tickets in South Korea alone, making it that country’s fourth biggest-selling film of 2019.

Grossing over $120 million worldwide, Parasite is director Bong Joon Ho’s seventh film and his most successful yet. Coming from a director whose films often feature marginalized characters fighting oppression (see Barking Dogs Never Bite, The Host, and most recently Snowpiercer), Parasite has been hailed as a lucid and straightforward critique of wealth inequality in South Korean society.

The film (spoilers below!) is widely seen as an allegory for the rampant class inequality and popular frustration at the lack of social mobility in one of Asia’s richest countries. Writing in Jacobin, Eileen Jones praised Parasite for going beyond simple allegorical overtures, claiming that it “crystallizes the experiences of being an underclass family grasping at a chance to ‘make it,’ and portrays it in such a way as to hurt you.”
