The first act of The Medium is so convincing you could almost believe it’s real—a portrait of rural Thai shamans and the uneasy inheritance of their gods. But as the story unfolds, belief begins to slip. The camera never stops rolling, even when no sane crew would keep filming, and what starts as gripping realism drifts into contrivance.
It’s an ambitious spin on the faux-documentary form, but one that occasionally forgets its own setup. The overlong runtime doesn’t help, stretching the tension until it frays. You start to wish for the brisk, matter-of-fact editing of a true documentary to bring the chills back into focus.
Still, it’s not without power. There are moments of genuine dread, and its blend of The Exorcist and folk horror lingers, even if the possession never quite takes hold. A haunting half-success—believable, until it isn’t.
