Onslaught: Honest Review — Is It Worth Watching? | 5.8/10

Onslaught is a competent B-movie that mistakes visceral gunplay for emotional stakes, delivering exactly what its poster promises and nothing more. Adam Wingard shoots the hell out of a desert standoff, but the film never bothers to give you reasons to actually care who survives it.

The plot (no spoilers)

Onslaught drops you into a desert where genetically engineered super soldiers have gone rogue, and a hardened Army sniper named Maya must protect her young daughter from these walking weapons. The premise is lean—almost aggressively so—and Wingard treats it like a high-concept siege film where location becomes character and explosions do the talking. It’s Aliens filtered through a testosterone haze, except without Ripley’s actual arc or the xenomorphs’ biological horror to justify the paranoia.

The film operates in a stripped-down, sun-scorched aesthetic that should feel claustrophobic but mostly just feels empty. Wingard moves the camera with purpose, cutting away from dialogue whenever he senses boredom creeping in, which tells you everything about the script’s confidence in its own writing. You’re meant to show up for the gunplay, the creature designs, and Adria Arjona looking furious in tactical gear, and if that’s your speed, the movie delivers exactly that transaction with no interest in overcomplicating matters.

Acting & direction

Adria Arjona carries the film on pure physicality and a scowl that could cut glass, though she’s rarely given dialogue that asks her to be anything more than competent and protective. Dan Stevens shows up as the commanding officer with the charisma of a military recruitment pamphlet, delivering exposition with the warmth of a text-to-speech engine. Eric Wareheim as the lead creature brings an unsettling physicality that’s genuinely the film’s most interesting element, even if he’s essentially a CGI-enhanced muscle group stumbling through set pieces.

Wingard’s direction is ruthlessly efficient—every frame serves the momentum of the next action beat, and there’s something almost admirable about how little patience the film has for character development or worldbuilding exposition. The cinematography leans hard into desaturated oranges and sickly greens, giving everything a vaguely nauseating quality that occasionally tips toward genuine unease. The score is aggressively functional, all synth-stabs and pulse-pounding drums that feel borrowed from a dozen other thrillers you’ve already forgotten.

The strengths

• The creature design—squat, asymmetrical, wrong in ways that stick with you—is the film’s single best creative choice and occasionally elevates the hackneyed monster-loose scenario into something genuinely unsettling.
• The 92-minute runtime means Wingard never overstays his welcome, and there’s a brutal efficiency to how quickly the movie moves from setup to carnage that respects your time even if it doesn’t respect your intelligence.
• Arjona’s sniper sequences actually land with kinetic satisfaction, and Wingard frames these shootouts with enough visual clarity that you can always track what’s happening in the chaos.

The weaknesses

• The mother-daughter relationship is painted in the broadest possible strokes—one emotional beat arrives so late in the film that it lands with all the impact of a whisper in a hurricane.
• The script treats the genetically engineered super soldiers as interchangeable threats rather than anything resembling an actual antagonistic force with motivation or presence beyond “they kill things.”
• Every supporting character exists only as exposition delivery systems or target practice, and the dialogue has all the authenticity of a military recruiting video written by someone who’d never actually met a soldier.

Who should watch it

If you’re hunting for a pure action thriller that doesn’t demand your emotional investment and you’ve already exhausted the obvious marquee names, Onslaught scratches that itch with mechanical precision. The film appeals specifically to viewers who loved the kinetic brutality of something like Annihilation or the creature-driven suspense of Tremors but would rather skip the character arcs entirely. This is desert popcorn for insomniacs scrolling at midnight, competent enough to hold your attention but forgettable enough that you won’t think about it five minutes after the credits roll.

Final verdict

The movie is a perfectly serviceable action-horror hybrid that understands exactly what it is and makes zero apologies for that ambition, which is either admirable or depressing depending on your tolerance for manufactured spectacle without substance. Wingard proves he can stage gunfights and creature encounters with genuine spatial clarity, but the film’s complete indifference to character or thematic resonance keeps it from being anything more than a exercise in technical competence. It’s the cinematic equivalent of a protein shake—functional, efficient, and utterly forgettable the moment it passes your lips. Watch it if you need 92 minutes of competent mayhem, but don’t expect anything that’ll linger or surprise you.
