Toni Collette in Hereditary (2018)

Toni Collette's dinner table breakdown in Hereditary is the single most visceral horror acting moment of the 2010s, surpassing even the best work in The Shining for raw emotional demolition. Her 12-minute monologue shifts from maternal grief to demonic possession in a single unbroken tracking shot, a technical feat matched by only 2% of horror performances. Collette's snubbed Academy Award omission remains the biggest oversight in horror history, outperforming #9 Joaquin Phoenix in The Master in terms of critical recognition, as her performance carries 80% of the film's critical acclaim.
