The Guardian reviews Adam Wingard’s “Onslaught,” highlighting Adria Arjona’s performance in a super-soldier slasher

“Onslaught,” a super-soldier slasher directed by Adam Wingard, is the subject of a new review by The Guardian published Aug. 31, 2026. The paper frames the film as a genre outing that blends a bigger, more mainstream approach with the sensibility of an independent filmmaker returning to familiar territory.

The Guardian’s review emphasizes Adria Arjona’s performance, describing it as committed and characterizing her role as “spunky.” The paper indicates that Arjona’s screen presence is one of the film’s main strengths, even as it evaluates other elements of the production.

According to The Guardian, the film is “decent” in the shape of a B-movie, but it “doesn’t go hard enough,” a critique presented in terms of how the movie delivers on the intensity expected from its subgenre. The review suggests that the movie lacks “sharper weaponry,” using the phrasing as a metaphor for the level of impact the story provides.

The Guardian also comments on the director’s career arc, writing about a “fascinating” pattern in which an indie director goes to “the A-list” before returning to their roots. The review characterizes Wingard’s work in “Onslaught” as operating within a stricter framework, with small creative choices treated as pre-agreed constraints rather than room for improvisation.

In the review’s description of that creative process, The Guardian indicates that “tiny” decisions are “agreed upon,” placing the film within what it presents as a more controlled production system. The implication in the review is that those constraints shape what the movie ultimately does on screen, for better or worse.

The Guardian’s publication of the review on Aug. 31 places it in the context of the film’s ongoing cultural conversation, with coverage focused on craft and performance rather than on corporate or labor questions. With only the review available in the reporting packet, no additional confirmed details about “Onslaught” release timing, distribution, or production credits were included here beyond the director and lead performer cited by the reviewer.

As of the review’s publication date, the primary publicly documented response in this packet remains The Guardian’s assessment of the film’s genre execution and cast work, with its headline conclusion centered on whether “Onslaught” meets the appetite audiences may bring to a super-soldier slasher. The next step for readers seeking further information is to consult additional outlets for consensus on the film’s direction, pacing, and overall impact across different viewing audiences.
