Bedevilled was one of the films that I didn't have time to fit in at last year's Frightfest but with its release on DVD this week I made good on a second chance.
While American horror and thrillers tend to languish in remakes and torture porn, it's great to see Korean filmmakers still finding ways to tell engaging and thought-provoking horror stories, as is the case with Bedevilled.
Bedevilled tells the story of city girl Hae-Won who, after an altercation at work, heads on vacation to an island to meet estranged childhood friend Bok-Nam.
It's here that Hae-Won witnesses the pressure cooker that Bok-Nam calls life. Bok-Nam is belittled by the village elders, abused by her cheating husband and forced to work on the farm.
Director Jang Cheol-Su notches up the tension slowly and brutally as we experience Bok-Nam's abuse on a daily basis.
Unlike I Spit On Your Grave or Last House on the Left, the brutality here isn't confined to a single incident; Bok-Nam's pain starts with sunrise and doesn't end at sunset. The pain is constant and sharp.
The beatings are tough to watch, but what makes them tougher is the sense of normalcy that the villagers have to witnessing them.
What's more, Hae-Won's apathetic "see no evil, hear no evil response" to her friend's situation implicates her as much as Bok-Nam's torturers.
Hae-Won isn't portrayed as vain or arrogant but rather as someone whose life in the city has allowed her to compartmentalise her friend as something less than human.
She's educated and privileged and yet she doesn't help her friend - a lazy form of evil.
When events come to head and tragedy strikes, Bok-Nam eventually decides enough is enough and takes arms against her oppressors and her friend.
The film is a slow-boil so that when the violence does erupt and revenge is taken, it's shocking, cathartic and ultimately sad - reminiscent of the denouement of Old Boy.
The film sees the evaporation of a friendship that could have saved two lives rather than the life of the one person left standing at the end of the film.
And that's the real horror that stays with you after the credits roll.
