The scariest film of the year so far and one of the creepiest entries in the world of horror in recent years, The Medium begins as a documentary about a shaman possessed by a local deity in North-east Thailand but soon develops into a dreadful & diabolical nightmare that you can't escape from. Powerful, petrifying & perturbing in equal measure, this Thai-South Korean supernatural horror reeks of death & devilry.
Co-written by Na Hong-jin (The Wailing) & directed by Banjong Pisanthanakun (Shutter), the film employs the faux-documentary format to narrate its tale of faith, inheritance, malaise & malison and gradually brings the viewers into its world of beliefs, curses & superstitions with its informative approach & natural acting from the cast. It takes its time, is never in a hurry & starts to ratchet things up only after the audience is fully on board.
While suffused with a feeling of something sinister & unholy brewing under the surface from the beginning, the film's horror elements lunges to the forefront only after the board is set & all the characters are properly introduced. And the execution is genuinely effective & nerve-wracking. There are scenes in here that are downright shocking & disturbing but what lends those moments their uncanny weight & power are the thoroughly convincing performances.
Overall, The Medium is one of those unnerving horror offerings that feels cursed, brims with an ill-omened quality and is smeared with a blood-curdling atmosphere that only intensifies as plot progresses. Intelligently directed, deftly scripted, finely detailed & strongly bolstered by Narilya Gulmongkolpech's bone-chilling act, the film does run longer than it needs to but the terror it invokes from its eerie setting & skin-crawling imagery is as unrelenting as it is unsettling. Don't miss it.
