Here’s the verdict up front: Autonomous is the rare “vertical horror” release that earns the word horror and uses the word vertical on purpose. As the debut of Screamify’s Micro Horrors™ banner, it sets a bar the format has badly needed.

The setup is a single, airtight idea: a self-driving rideshare locks its passenger in and drives toward a destination she didn’t pick. “Your ride knows the way. So does something else.” Producer-star Erin Áine and director Kyle Valle (Big Squid) wring genuine claustrophobia out of one location and a runtime measured in minutes.

‘Autonomous’ Review: Screamify’s Micro Horrors™ Debut Is a Lean, Mean Vertical Scare

What Works

Almost all of it. The 9:16 frame turns the car into a vertical trap and keeps Áine’s face — and her escalating panic — right in front of you. The blue-lit interior is a great-looking, legitimately tense piece of craft, and the pacing respects your time: no filler, no fat, just tighten-and-twist. Screamify backing it with the Behind the Screams docuseries shows a studio treating short-form like a real production, not a content dump.

Behind the Screams — Screamify’s original docuseries on the making of “Autonomous.”

What Keeps It From a Perfect Score

One thing, and it’s almost a compliment: we wanted more of the monster. The glimpses we get are genuinely terrifying — a design with real teeth — and the film’s restraint, while smart, left us craving a fuller reveal. When your only complaint is “more, please,” the debut has done its job.

SCREAM SCORE: 8.5. A lean, sharp, genuinely scary proof-of-concept for Micro Horrors™ and for vertical horror as a real form. Bring on the monster — and the next one.
