Overview
- Embargoed reviews released Aug. 31–Sept. 1 delivered a mixed‑to‑positive consensus, with early aggregator tallies running about 73% on Rotten Tomatoes and roughly 60/100 on Metacritic.
- Critics repeatedly singled out the film’s synth-heavy score, Carpenter‑like aesthetic, tight cinematography and practical gore as its chief strengths.
- The most common criticisms were structural: reviewers said much of the first hour is devoted to setup and that the third act loses momentum, leaving the climax feeling undercooked.
- Onslaught stars Adria Arjona as a former Army sniper who must defend a trailer‑park community from a trio of genetically enhanced super‑soldiers created by Dan Stevens’s Dr. Hans Kammler, and reviewers note the film uses military‑industrial themes as texture rather than focused critique.
- A24 will release the R‑rated, roughly 90–92 minute film in theaters on Sept. 4, and industry coverage frames it as a niche, mid‑budget genre return for Wingard rather than a mainstream blockbuster.
