The Medium (2021)

Another found-footage horror done so, so right, this Thai-Korean chiller (directed by Banjong Pisanthanakun and produced by Na Hong-jin, whose eerie The Wailing is also a recommended Shudder pick) styled like a documentary starts off chronicling the interesting but not especially pulse-pounding life of a shaman who serves as the vessel for a benevolent goddess, a spiritual duty that’s part of her family legacy. Things perk up when the goddess’ spirit decides it’s time to jump into the next generation, in the form of the shaman’s unwilling niece… and then take a turn for the highly alarming once the documentary crew (and with them, anyone watching The Medium) starts to realize there’s even more horror to the story than they realized, leading to a truly shocking final act.
