You know, I kind of liked this movie. What should have been a standard C-grade teens-getting-picked-off-in-a-remote-location horror movie packs some genuine creepiness in there, as teens in the deserve inadvertently summon a... well, it never explains exactly what the "Hisji" evil entity really is, but it can fuck with electricity and confuse the hell out of its victims before offing them. More about building mood than jump scares or gore, and while it isn't a great film, or even a very good one, it definitely has that going for it, and I liked it for that. Way less crappy that, say, "Candyman". In fact, not really crappy at all, just kind of... only-moderately-unambitious, at worst. The AV club has a pretty good review at https://film.avclub.com/one-of-the-biggest-horror-movie-scares-of-the-year-happ-1835452053, saying all the scares happen in well-lit scenes, and that this is not "don't go in the basement" horror, which is a good way of putting it.
