This film’s review was written after its screening at the South by Southwest Film Festival in 2026.

With the rise in too-large-to-fail corporations exerting escalating control over the population, the horrors of capitalism persist through the weaponization of bureaucracy, amongst other things. When companies obscure their business practices from the public eye, it makes it harder for abuses to be corrected. We all lose when companies like Uber refuse to put in safeguards for women passengers and drivers subject to harassment or when businesses like Amazon force their drivers to complete impossible routes with no breaks. Without protections from big corporations, we all stand to lose something. 

The latest victim to corporate neglect is Julia (Britt Lower), an underemployed artist who is attempting to get sober. One day, mysterious packages begin showing up at Julia’s front door. At first, her confusion turns to irritation at the extra items before it transforms into full blown paranoia. When the volume of items increases, the item’s curiously pointed utility in her life causes Julia to believe someone is stalking her to know exactly what she needs. She enlists the help of her introverted delivery driver (David Dastmalchian) to get to the bottom of the Smirk company’s business practices. Outside of him, the support in her life is relegated to her distrustful yet overly helpful sister (Anna Baryshnikov) and Whitney (Rhea Seehorn), a woman she meets at her support group.

Dizzying and exhausting, Sender is a well-crafted, if repetitive, psychological horror drama.

Chaotic editing and its tendency to indulge in stream-of-consciousness storytelling allows Sender to disorient its viewer as much as Julia descends into paranoid madness. Overlaying the absurdly persistent influx of mail arriving at her place amongst Julia’s increasingly frazzled responses to the packages, Sender better characterizes the overwhelming weight of paranoia it injects in the narrative. It’s impossible not the sympathize with the sheer irritation that Julia’s situation would inspire, let alone the dangers it spells. Working to the film’s advantage, the haphazard manner in which the story is assembled plays well to the greater themes of Sender.

It’s all done in service of better understanding Julia’s state of mind. The process of quitting alcohol, or any drug, has a profound effect on one’s mental faculties, not even considering the very real physical effects of withdrawal too. Her psychological state is already delicate before the packages even arrive. Sender juices up the tension by exploiting this dynamic. Is Julia’s situation improving from her interventions or is she just making it worse? Britt Lower sells Julia’s volatility in the face of her harassment.

A leading force in her own destruction, Julia is a delightfully unhinged train wreck who is impossible to ignore. Throughout Sender, it’s clear that Julia gets in her own way when trying to solve her own problems. Impulsive, irrational, and self-involved, Sender makes a point to lay into Julia every time she hurts another person in her life. As her psychological state deteriorates, so does Julia’s ability to make good decisions. Despite all this, neither in suffering through her addiction nor this new dilemma, Julia tries. It’s in her insistence to never give up that makes the B-plot of Sender hold sufficient weight.

Sender forces the audience to reflect on how her feelings of powerlessness worsens Julia’s situation and is entirely predicated on the Smirk company [a dupe of Amazon] refusing to help her. Her terror is entirely reliant on the corporation’s inability to see her humanity in the problem facilitated by their service. Sender raises important questions about the social contracts we enter with businesses and how they increasingly ignore them to prioritize the needs of CEOs and shareholders. 

The bones are present, but Sender doesn’t build on the foundation sufficiently to fully flesh out the tale. By the time all the answers arrive, Julia’s situation feels arbitrary and underwhelming. It diverts from the larger topics Sender tries to breach without matching the tonal intensity or overall goals of the story. In short, Sender fails to resolve either storyline or say something interesting with its unfulfilled story threads.

At times interesting but never quite spellbinding in its approach to psychological horror, Sender is a plodding, well-executed character study that works well enough for genre fans. Solid production values and a compelling story foundation leave plenty for Sender to mine regarding the important questions it poses. Unfortunately, uneven pacing and an underwhelming approach to the subject matter makes it hard to fully appreciate the horrors of labor and consumer abuses in the United States. 

Overall Score? 6/10
