Richard Lawson, in his review for Vanity Fair, called the film "cold" and "unlovable."
I’m being vague here because the particulars of Sacred Deer’s plot are probably best left unspoiled. I think I can safely tell you that the film is about a heart surgeon (a muted Colin Farrell) and his wife (Nicole Kidman, bringing her familiar watchful glow), also a doctor, who find themselves in a nightmarish predicament when a peculiar teenage boy named Martin (Irish up-and-comer Barry Keoghan) enters their lives. There’s a terrifying, atavistic form of justice and revenge at work in Sacred Deer, a reckoning for past sins that turns the film into something of a classical tragedy, albeit one with a decidedly modern sense of cynicism and wit.
Lawson compared the film's "elemental horror" to that of "The Shining."
The Independent reported the film was booed, despite its big win at the festival.
David Ehrlich of IndieWire called the film a "Sophie's Choice" remake; The Los Angeles Times' Steven Zeitchik called it "the most chilling horror film imaginable," and Alex Billington of FirstShowing.net said "you'll either love or despise this movie."
Dr. Mario Castillo-Sang, a cardiac surgeon at Christ Hospital, showed Farrell the ins and outs of surgery. Castillo-Sang said he took part in an operating scene in the film – but that’s about all he could say. He described the film as dark and interesting.
One Christ Hospital employee impressed the director so much, he was given a speaking role.
Herb Callouet, executive director of Christ Hospital’s Joint and Spine Center, was giving Lanthimos a tour when the director offered him a role in the film as a hospital administrator.
“It was a got-to-be-kidding-me kind of moment,” he said. “I never thought in any way, shape or form what would come about.”
