Today I learned that Indonesian horror cinema, much like the local version, sometimes goes back to the well. Because it turns out that Satan’s Slaves is a remake of the same title in Indonesian (although Satan’s Slave, singular, in English), made in 1982. I haven’t seen that one, but the IMDB summary makes it clear they’re related.
Anyhow, this version starts with the quiet grief of a family whose once-famous singer matriarch is withering away from a mysterious illness. Not only are they losing their mother (or, in one case, wife), but they’re also losing the things they own and quite possibly their house, in paying for her care. I guess mostly the medicines and old doctor bills, as the mother is in house and being cared for by the family, not a hired nurse or anything.
But then things get flickery at the edge of your vision ghosty, and then they get in your face ghosty, and then things get a lot worse than that, in unexpected ways. (Or, well, maybe not so unexpected, based on the title.) Despite a third act full of running and hiding and fighting with generally about triple the cast of anything that has gone before, the movie as a whole is quiet and meditative albeit with occasional actual scares (and more than a few attempted jump scares). Meditative on how families might dissolve, on the kind of loss that we all someday face, on falling away from your religion, and most especially on how the sins of the past must be paid, even if they weren’t your sins.
