However, when Steven's own children begin suffering a clinically unexplainable condition things begin to unravel. Steven's relationship with Martin takes a peculiar and sinister turn when Martin offers Steven a horrific solution to their problem.
Farrell and Kidman offer typically measured performances, but the real surprise is Barry Keoghan (Dunkirk), whose portrayal as Martin feels like watching a toddler with his hand on the proverbial nuclear button.
It is a tour de force of uneasy acting that delivers the perfect balance of ambivalence and malevolent intention - his character taking on an almost biblical role (suggestive of the binding of Isaac) that is central to the film's exploration of what it means to atone for our transgressions.
The Killing of a Sacred Deer will no doubt divide its audience. The awkward mix of unconventional storytelling and inaccessible characters might be too impenetrable for some. For others (myself included), The Killing of a Sacred Deer remains a macabre psychological satire told in a very unique and refreshing way.
