Passenger is a highly effective, incredibly tense supernatural thriller that breathes fresh, malevolent life into the road-trip horror subgenre, turning the concept of "van life" into a rolling prison of psychological dread. Director André Øvredal masterfully uses the cramped confines of a vehicle and the isolating darkness of the open road to build a slow-burn masterclass in atmospheric tension. The supernatural elements are handled with great restraint, relying heavily on deep shadows, sudden shifts in perspective, and excellent sound design rather than cheap jump scares. Grounded by strong performances that keep the stakes intensely human, the film excels at maintaining a white-knuckle pace. Backed by gorgeous night-time cinematography and a relentless sense of isolation, it delivers an incredibly solid, genuinely spooky horror experience.

"Tyler" (Jacob Scipio) and "Maddie" (Lou Llobell) are a young couple who have decided to abandon the urban rat-race. She has done some interior design work on their old van, and so the pair set off for a life on the road. To be fair, she is a little less convinced by the romance of this new lifestyle and that only gets worse when they witness a nasty road accident on their first night out. That's just the start of their horrors though as things quite literally start going bump in the night. Is their new home possessed by some malevolent spirit? Well at a chance meeting at a camp of similar travellers, they are advised by "Diana" (Melissa Leo) of a code of conduct to protect them from the menacing "Passenger". That legend all stems from the story of St. Christopher who journeyed the land with a colleague whom everyone assumed was just as benign. It turns out, though, that this companion was in fact a demon who, now replete with his own dog collar, is bent on murderously terrifying all who make the mistake of stopping on the roadside after dark. This is all very procedural stuff and neither the acting nor the writing offer us anything new, but the use of the dark and the largely rural settings, coupled with some fairly intense camerawork and audio editing leaves us with what is, at times, quite a scary little thriller that has a denouement that I did rather enjoy. No, you'll never remember it and it slots nicely into the genre's production-line approach to movies, but it's watchable enough.
