Onslaught, the new action-horror thriller from director Adam Wingard, marks his return to the lean, genre-driven filmmaking that first made his name before a decade spent on studio tentpoles such as Godzilla vs. Kong. In this Onslaught review roundup, the reception is largely positive but far from unanimous, with critics broadly agreeing on the film’s visceral craft and Adria Arjona’s star-making performance, while remaining divided over whether its scattered plotting and thin characterization hold the whole film together.
The film follows Celeste, played by Arjona, an Army veteran and sniper living in an isolated desert trailer park with her young daughter, Daisy. When a military science experiment goes catastrophically wrong, three nearly unstoppable genetically engineered super-soldiers escape a nearby facility and descend on the trailer park, forcing Celeste into an increasingly bloody fight to protect her family and neighbours over the course of a single night.
Several reviews responded enthusiastically to the film’s throwback genre energy. SlashFilm’s Ryan Scott described it as a synth-heavy, unabashedly violent grindhouse-style collection of Carpenter-esque elements, while IndieWire’s Wilson Chapman praised the tactile impact of the action and Wingard’s willingness to cover his actors in copious amounts of fake blood.
AwardsWatch was similarly positive, calling it a wild ride worth sticking with despite its structural weaknesses. The Playlist also argued that, as an action-exploitation film, Onslaught knows exactly what kind of movie it wants to be, awarding it a B-.
Across nearly every review, Adria Arjona’s performance emerged as the film’s most consistently praised element. Variety highlighted the toughness and flashes of warmth she brings to Celeste, particularly in her protective and maternal moments. IndieWire credited Arjona with elevating relatively thin material through an exhausted, uncompromising performance that remains consistently watchable.
TheWrap’s more mixed review nevertheless conceded that Arjona makes a convincing case for herself as a future action star, provided she finds material that matches her abilities. Dan Stevens, who plays the Nazi scientist responsible for the super-soldier programme, also attracted attention for fully embracing the film’s campier instincts. The Hollywood Reporter singled out one particularly bizarre sequence involving his character.
Other critics were considerably less forgiving of the film’s structure. The Hollywood Reporter, in a review headlined “Tons of promise, not quite enough payoff,” praised Wingard’s eye for vivid and unsettling details but ultimately felt that the film did not fully deliver on its premise.
Variety similarly described the film as fun but scattered, suggesting that it is not the most polished entry in Wingard’s output and could have benefited from another screenplay pass. TheWrap was harsher, arguing that the film lacks meaningful character development and a particularly coherent theme, while also noting that the titular onslaught arrives surprisingly late.
Much of the critical conversation has also centred on what Onslaught represents for Wingard as a filmmaker. After spending recent years working on the Godzilla vs. Kong franchise, Wingard has reunited with longtime collaborator Simon Barrett, the writer behind You’re Next and The Guest, for the new film.
The Playlist described the result as a lean, loud, heavy-metal B-movie action thriller that embraces the low-budget menace associated with early James Cameron and John Carpenter. Even critics who found the film uneven, including TheWrap, acknowledged the significance of Wingard returning to smaller and stranger material, although that review argued that his Godzilla films were ultimately more creative and unhinged.
Taken together, the reviews describe Onslaught as a loud, bloody genre throwback anchored by a standout performance from Adria Arjona, even as critics remain divided over whether its scattered plotting undercuts the fun. Whether viewed as a gloriously scuzzy midnight movie or a promising return that needed another screenplay pass, Onslaught arrives with a clear genre identity and a critical response that, while not unanimous, leans positive.
