The Medium, a 2021 Thai horror film directed by Banjong Pisanthanakun and produced by The Wailing’s Na Hong-jin, is a haunting blend of found-footage storytelling and cultural horror. Set in the Isan region of Thailand, the film follows a documentary crew as they explore the life of a local shaman, Nim, who is believed to be the vessel of a benevolent spirit named Ba Yan. But what begins as a respectful cultural exploration quickly spirals into something far more sinister.

👁️‍🗨️ What to Expect

• 🇹🇭 Authentic Thai Folklore: The film deeply immerses you in local shamanistic beliefs and rituals rarely seen in mainstream cinema.

• 🎥 Found-Footage Format: The documentary style adds a layer of realism and dread, making the supernatural elements feel disturbingly plausible.

• 👻 Terrifying Possession Sequences: The horror here doesn’t hold back—visceral, raw, and deeply psychological.

• 🧠 A Slow-Burn Build-Up: The tension gradually escalates, keeping you on edge until its chaotic and unforgettable climax.

As the documentary crew begins to witness strange, escalating supernatural events—centered around Nim’s niece, Mink—the line between spiritual possession and mental illness blurs. What follows is a descent into terror that’s both spiritual and physical, culminating in one of the most intense final acts in recent horror cinema.

👹 Verdict

The Medium is not just a horror film—it’s an experience. It’s a dark, unnerving dive into Thai spiritual beliefs that blends realism with pure nightmare fuel. While its pacing might feel slow for some, the payoff is more than worth it. It’s unsettling, thought-provoking, and utterly terrifying.
