Rating: 6 out of 10

Onslaught (2026) brings director Adam Wingard and writer Simon Barrett back to the kind of gritty genre filmmaking that helped establish their reputations. Blending action, horror, thriller elements and a distinctly retro aesthetic, the film feels like a loving salute to the outrageous movies of the 1980s. While its ambitious premise promises a much wilder experience, Onslaught still delivers enough atmosphere, violence and personality to make it an entertaining watch.

Adria Arjona Gives the Film Its Strongest Punch

At the centre of the story is Celeste, an Army veteran who now runs a trailer park while sharing custody of her young daughter, Daisy. Her quiet life is shattered when three genetically engineered super soldiers escape from a classified military facility and arrive in the desert community. With her daughter in danger, Celeste must confront the combat instincts and painful memories she thought she had buried.

Adria Arjona is easily the movie's biggest strength. She balances Celeste's toughness with vulnerability, making her feel like more than a conventional action heroine. Her chemistry with young Blake Kennedy also gives the film an emotional core that prevents the story from becoming purely blood-and-bullets entertainment.

A Promising Opening That Loses Momentum

Onslaught makes an immediate impression. Its explosive opening introduces Celeste as a dangerous and capable survivor without drowning the audience in exposition. Freeze-frame title cards, retro-inspired credits, and Matthew Pusti's pulsing synth score establish the film's throwback identity almost instantly.

A recurring countdown mechanism adds another layer of anticipation, constantly suggesting that a major eruption of violence is just around the corner. However, the movie struggles to maintain the pace established during its first act. The middle portion becomes more focused on Celeste's military history and the origins of the enhanced soldiers, temporarily taking attention away from the central survival conflict.

Bloody Action Meets Atmospheric Horror

When the action finally explodes, Onslaught delivers several enjoyable bursts of brutality. The practical gore gives the violence a satisfying physical quality, while the desert trailer-park setting creates an isolated and uneasy backdrop.

Cinematographer Oren Soffer deserves credit for making the modest setting look cinematic. The nighttime sequences are particularly effective, using shadows, lighting, and carefully composed frames to create a sinister atmosphere. Still, some action sequences end just when they begin to get exciting, leaving the film feeling less ferocious than its premise suggests.

A Fun Throwback That Could Have Gone Further

The supporting cast, including Dan Stevens, Eric Wareheim, Alex Pereira, Michael Biehn, and Reginald VelJohnson, adds personality to the ensemble, although several characters deserved greater development.

Overall, Onslaught is a stylish and enjoyable action-horror throwback that comes close to being something truly explosive. Wingard and Barrett clearly understand the visual language of vintage genre cinema, while Arjona gives the film a compelling emotional centre. Its uneven pacing and restrained set pieces prevent it from reaching its full potential, but the atmospheric visuals, practical gore, and retro energy make it worth a watch.
