The Medium (2021)

The Medium feels special because it doesn’t treat possession as a theme-park scare—it roots its horror in lived-in places, family history, and the uneasy overlap between faith and fear, so the dread seeps in before it ever explodes. Shot in a convincing mockumentary style, it builds the kind of realism that makes you lean forward, and Narilya Gulmongkolpech’s performance is so committed it’s hard to look away even when you want to. Director Banjong Pisanthanakun uses Thai and Isan spiritual traditions not as window dressing but as the engine of the tension, giving familiar genre beats a fresh, unsettling texture. Fair warning: it’s a slow-burn that turns into something brutally intense, with graphic, disturbing imagery—so it’s not for the squeamish—but if you want horror that feels culturally specific, emotionally grounded, and relentlessly escalating, this one delivers.

The Medium is aiming for a slow-burn, faux-documentary descent into spiritual horror, using Thai shamanism and family guilt to make the possession feel culturally specific rather than generic. When it works, it’s genuinely creepy and grounded, with strong committed performances and an unsettling sense that something is deeply wrong long before the big scares arrive. But be warned: it’s long, structurally bloated, and eventually trades tension for a chaotic, shock-driven finale that leans hard on familiar found-footage and possession beats. If you’re sensitive to explicit sexualized possession content or severe, graphic violence, or you prefer tight, psychological horror over messy escalation, this one may feel more punishing than rewarding.
