The brief

Corin Hardy turns a genuinely creepy Aztec artifact into the centerpiece of a surprisingly effective supernatural slasher that knows exactly what it's doing. The death whistle itself is nightmare fuel - its bone-chilling sound design will stick with you long after the credits roll - while Dafne Keen anchors the group of teens with the kind of grounded performance that makes you actually care when things go sideways. Hardy maintains a relentless pace once the bodies start dropping, building genuine dread rather than relying on cheap jump scares. Perfect for fans of Final Destination's inventive kills mixed with The Descent's archaeological horror mood.

The verdict

If you love supernatural slashers with inventive kills and can appreciate horror that builds genuine dread through effective sound design and solid performances, this is a satisfying genre entry that delivers on its creepy premise. If you need critical acclaim or polished storytelling over atmospheric scares, the mixed reviews suggest you should wait for something with stronger execution.
