The Medium (2021) Review: Mockumentary Shaman Horror from Thailand

Is The Medium worth watching?

Yes — especially if folk horror and fake documentaries overlap in your taste map. The Medium holds an 82% Critic Score, 70% Audience Score, 74 Metascore, 3.5 on Letterboxd, and 6.8 on IMDb. Banjong Pisanthanakun — co-director of the beloved romance Phobia 2 segments and One Day — joined forces with Korean producers to mount shamanistic horror that played Cannes and Shudder.

What is The Medium about?

A documentary crew follows a family of Isan shamans as niece Ming exhibits signs of possession during rituals meant to channel a local goddess. Narilya Gulmongkoltree, Sawanee Utoomma, and Yasmin Kassim anchor performances that blur faith, performance, and genuine terror. The camera becomes a participant — viewers debate whether the crew’s presence causes the catastrophe.

Should you watch The Medium with Indonesian horror?

Yes — pair with Joko Anwar’s Satan’s Slaves and Impetigore for Southeast Asian spiritual horror at different temperatures. Kevin Ko’s Incantation from Taiwan offers found-footage curses with similar participatory dread. Awi Suryadi’s KKN di Desa Penari delivers populist Javanese scares without mockumentary framing.

How does Banjong Pisanthanakun handle the mockumentary form?

By respecting Isan ritual long enough that the shift into chaos feels like betrayal rather than gimmick. The first hour builds ethnographic detail — offerings, family hierarchy, Ming’s resistance — so when possession accelerates, the horror inherits documentary credibility. Kaiser Khan’s split verdict: some critics found the finale overcooked; others argued the escalation is the point — faith systems collapsing under camera lights.

Where does The Medium rank in the decade?

Among Thailand’s most exported horror titles — the bridge between domestic folk belief and Korean co-production muscle. On Best of Asia 2016–2026 it sits beside Nattawut Poonpiriya’s Bad Genius as proof Thailand exports more than romance and comedy. Shudder streams in many territories; IMDb tt13403478.

Who should watch The Medium tonight?

Horror fans who liked Incantation’s ritual participation; viewers curious about Isan shamanism; anyone building a Southeast Asian folk horror syllabus. Not ideal for jump-scare-only audiences — patience required.

Why did The Medium divide critics on its finale?

Because Banjong Pisanthanakun escalates from ethnographic patience to chaotic possession set pieces — some viewers wanted mockumentary restraint throughout. Others argued escalation is inevitable once cameras enter sacred ritual. Korean co-production influence shows in scale; Thai setting keeps folk detail authentic. Rewatching first hour after finale changes interpretation of Ming’s early resistance.

How does this title fit Celluloid’s Asia map?
