Review: Onslaught

Onslaught sounds like Adam Wingard returning to the sweet spot that made You’re Next and The Guest feel like jolts of genre electricity: a lean, mean, blood-slicked siege movie about a traumatized veteran, her daughter, a desert trailer park, and a trio of genetically engineered super soldiers unleashed by the sort of government program that seems to have been funded entirely by paranoia and bad ideas.

For a while, that promise is enough. Wingard opens the film with a grab bag of lurid images and nasty implications, treating conspiracy culture less as plot architecture than as atmosphere. There are secret labs, old fascist rot, military experimentation, and shadowy men who seem less interested in covering up a disaster than in seeing what kind of data the disaster produces. The movie is proudly ridiculous, but it is not random. It understands that modern pulp no longer needs to invent distrust in institutions. It only has to turn the volume up.

At the center is Celeste (Adria Arjona), a former Army sniper living with her young daughter, Daisy (Blake Kennedy), and managing the Windy Oasis trailer park with the brittle patience of someone who has already survived more than enough. Arjona gives the film its pulse. Celeste could have been a simple action-movie outline: mother, soldier, survivor, weapon. Instead, Arjona plays her as someone whose competence is inseparable from damage. Her alertness feels exhausting. Her toughness is not swagger but scar tissue. When violence finally comes for her home, she does not transform so much as reveal the version of herself she has been trying, not always successfully, to keep holstered.

That is where Onslaught works best: as a showcase for Arjona, who proves she can carry both the bruised emotional weight and the blunt-force physicality of an action lead. Wingard knows how to frame her, and the movie gives her the kind of grim, practical heroism that has gone missing from too many modern genre exercises. Celeste is not invincible, and the film is better for it. Every reload, every wound, every panicked decision seems to cost her something.

Around her, the movie assembles a pleasingly strange supporting cast. Dan Stevens, as deranged scientist Hans Kammler, attacks the role with the commitment of an actor who has never met a grotesque flourish he could not make somehow elegant. Drew Starkey makes a strong impression as Cyrus, a cleanup man whose calm suggests an entire HR department for atrocities. Reginald VelJohnson brings welcome warmth and action-movie ballast as Josiah, while Rebecca Hall turns a small role into a decadent little detour that briefly suggests a much weirder, more dangerous film hiding just outside the frame.

The trouble is that Onslaught keeps suggesting that better, stranger film without fully becoming it. Wingard and screenwriter Simon Barrett have built a world of promising details, but the movie’s structure is almost aggressively basic. Once the super soldiers arrive, the film settles into siege mechanics that are sturdy but rarely surprising. The villains look imposing, and there are moments of satisfyingly nasty violence, but the action does not escalate with the deranged invention the setup seems to demand. For a movie called Onslaught, it occasionally feels oddly measured, as if it is admiring its grindhouse poster from across the room instead of tearing it off the wall.

That restraint might not matter if the film’s political anger cut deeper.

Onslaught gestures toward veterans discarded by the systems that shaped them, toward militarized cruelty, toward the way fascist ideas survive by changing uniforms. Those ideas give the movie texture, but they remain mostly texture. Wingard is excellent at conjuring the mood of American rot, less successful here at making that rot feel specific. The result is a movie with the iconography of outrage but not always the force of it.

Still, there is pleasure in watching Wingard operate at this scale again. His craft is muscular, his sense of tone remains sharp, and even when Onslaught underwhelms, it rarely feels anonymous. It is too vivid to dismiss and too undercooked to fully champion. As a return to scrappy genre filmmaking, it has teeth. One only wishes it bit harder.

Onslaught is a bloody, stylish, intermittently thrilling B-movie that gives Adria Arjona the action showcase she deserves, even if the movie around her never quite lives up to its own beautifully deranged promise.

3.5/5
