There's Someone Inside Your House (2021)

There's Someone Inside Your House arrives as a Netflix slasher with a life-like mask gimmick and a small-town Nebraska setting. The killer stalks Osborne High students while wearing replicas of their faces, a tidy visual metaphor for the age of screenshots and receipts. The cast is more varied than the genre usually bothers with: Sydney Park leads as Makani, a transfer student from Hawaii, and her circle includes Black and Latino friends and a gay classmate named Caleb. That diversity is not incidental, but it is also not the engine. The engine is shame.

Caleb's assault and subsequent shunning give the film its most pointed material; the killer's eventual justification for stabbing him involves Caleb trying to hide his homosexuality, which is ugly and specific. A student council president's racist and homophobic podcast gets aired as punishment, and the town's resentment of Zach's father, a billionaire farmland trader, adds a faint eat-the-rich hum. These are modern pressure points, and the film treats them as slasher furniture. The premise is essentially a lecture delivered through a knife: everyone has secrets, the mob is hypocritical, and the mask is the message. That gives the proceedings a preachy, of-the-moment texture, though the script rarely pauses to interrogate race beyond the podcast reveal.

Makani is a capable final girl who kills the killer, yet the role stays within genre tradition; her competence is not paired with an explicit feminist argument. The film has no interest in climate, body positivity, neurodivergence, or rewriting history. It wants to be a teen horror movie about callout culture, and it succeeds mostly as a messy time capsule. The result is a slasher that has read the room and decided to stab it.
