Overview
- Reviewers broadly praise Adam Wingard’s return to mid‑budget horror for its Carpenter‑inspired visuals, synth score and explicit, practical gore but criticize its storytelling and suspense.
- The film centers on a German scientist’s experiments to create engineered supersoldiers whose breakout brings violence to a truck stop and a desert trailer park that veteran manager Celeste must defend.
- Adria Arjona anchors the cast as Celeste and reviewers single out supporting work from Dan Stevens, Rebecca Hall, Drew Starkey and Reginald VelJohnson even as they say many characters are underwritten.
- Critics argue the movie wastes setup, rushes or disposes of characters without payoff, suffers pacing problems across its roughly 90–92 minute runtime, and lacks a satisfying third‑act resolution.
- Positioned by A24 as an R‑rated, tightly styled genre piece, Onslaught is being read as a niche, show‑style exercise that highlights Wingard’s practical‑effects craft but is unlikely to broaden his mainstream critical reach.
