**Early critic screenings have positioned "Onslaught" with an 85% Tomatometer on Rotten Tomatoes from the initial 13 reviews, driven by strong praise for Adam Wingard’s return to visceral, Carpenter-influenced action-horror.** Critics highlight the film’s brutal set pieces, synth score, and genre-blending energy, with outlets like IGN awarding 9/10 for its “down-and-dirty” thrills and others noting satisfying gore and midnight-movie appeal. A24’s backing and the director-writer team’s prior cult hits add momentum, though some reviews flag narrative thinness and a scattered structure that could temper the final score. Metacritic currently sits at 55 (mixed) from a similar sample. The wide theatrical release on September 4, 2026—Labor Day weekend—will trigger additional reviews that typically solidify or shift the aggregate in the days following. Traders should watch for post-release critic consensus and any late adjustments before the score locks.
