The cast includes Colin Farrell and Nicole Kidman; they play a husband and wife who are tormented by an unstable teen.
The unstable teen (Barry Keoghan) somehow sickens Farrell and Kidman’s children, and then gives Farrell a choice: Choose one member of his family to die, or they all will.
And the tension rises and rises, ultimately building to a truly transgressive conclusion.
On paper, The Killing of a Sacred Deer doesn’t look like a good Halloween movie.
