**Early critic reviews following the August 31 embargo lift have established a solid "Fresh" Tomatometer standing for A24’s Onslaught, with scores hovering in the low-to-mid 80s based on roughly two dozen reviews.** Adam Wingard and Simon Barrett’s return to compact, high-concept genre filmmaking—blending military sci-fi, slasher horror, and action—has drawn praise for its visceral set pieces, visual style, and brisk 92-minute pace, evoking John Carpenter-era energy while leveraging Adria Arjona’s lead performance as a protective army sniper. Mixed Metacritic scores around 52–60 reflect some criticism of narrative looseness and undercooked plotting, creating a gap between aggregator metrics that traders often monitor. With the wide theatrical release arriving September 4 on Labor Day weekend, additional reviews and the eventual audience Popcornmeter will determine whether the score holds or shifts amid competition and word-of-mouth.
