Early critic screenings for Adam Wingard’s A24 action-slasher *Onslaught* have driven an 85% Tomatometer on Rotten Tomatoes from the first 13 reviews, with praise centering on its unabashedly violent, Carpenter-inspired B-movie energy, practical effects, and Adria Arjona’s lead performance as a trailer-park sniper. Reviewers highlight satisfying action set pieces and retro grindhouse style while noting occasional narrative thinness or scattershot plotting. Metacritic’s 55 score reflects a more mixed aggregate from similar early coverage. With wide release set for Labor Day weekend against competing action titles, additional reviews could solidify or shift the final certified score as the market weighs the film’s cult appeal against its mainstream execution.
