**Onslaught**, Adam Wingard’s A24 action-slasher starring Adria Arjona and set for wide release on September 4, saw its review embargo lift on August 31. Early Tomatometer scores landed in the low-to-mid 80s percent range on roughly a dozen to two dozen reviews, with critics highlighting the film’s brisk 92-minute runtime, gory practical effects, and throwback B-movie energy reminiscent of Wingard and Simon Barrett’s earlier work like *The Guest*. Some reviews note narrative thinness and uneven pacing, reflected in a Metacritic average near 54. With Labor Day weekend competition and additional reviews still incoming, the final certified score hinges on whether the positive action and style momentum holds or if more mixed notices pull it lower before the market settles.
