(No significant spoilers except in the very last paragraph.)
The film Parasite won the Oscar for Best Picture. It was the first foreign film to have ever done so. It's a South Korean film.
The premise is a poor and unemployed family consisting of a father, a mother, a teenage son, and a teenage daughter end up conning and weaseling themselves into working for a rich family. The father serves as their limo driver, the mother as their house maid, the son as an English tutor for the rich family's daughter, and the daughter as the rich family's youngest son's art therapist. They forged documents to pretend like they have college degrees and work experiences they don't. The rest of the film unfolds from this setup.
I think one could evaluate the film on at least three different levels: a thriller with some dark comedic elements, a critique of "crazy rich" Asian culture, and social commentary (if not metaphor) about contemporary class warfare. Let's consider each of these.
