The Housemaid ending explained

What happens

The maid kills the family's son and forces Dong-sik into a suicide pact. They die of rat poison as his wife watches. Then Dong-sik turns to the camera and tells you it was only a warning that this could happen to any husband.

The last image

Dong-sik, alive again in the family's everyday life, speaks straight to the audience, turning the whole story into a cautionary tale.

Three readings

1 · A moral fableThe horror was never meant to be real; it is a warning told with a straight face.

2 · Imagined nightmareThe cut back to normal life suggests the catastrophe may have been a husband's fear or fantasy.

3 · Joke or lessonKim never lets you decide whether he is being serious or playing with you.

What it says

The maid exposes what the family hides: fragile status and a husband's repressed desire. By ending with a direct address, Kim stops you from watching safely and asks you to look at your own home, and at who holds it up.
