Are we supposed to understand what's going on in this?
I get that the housekeeper is supposed to be the ghost of the friend/rival who died in the car accident and that she is directly responsible for many of the deaths that occur.
Or do deaths occur at all? The weird ending implies that it was all some kind of weird vision, while our heroine was narrowly avoiding another car accident.
(More spoilers to follow, not all censored. Read on at your own risk.)
But then there's the ominous text messages - that seem to originate from the husband's phone? (I may have misunderstood that part, but it seemed to me that the cop was telling her the only texts she'd received were from her husband.)
And the sister who gets a fake phone call from her fiancee?
And the whole time-warp ending?
And the mute girl causing the younger one to fall?
I'm guessing at least some of this might make more sense if I were familiar with Korean traditions about what ghosts are capable of. Apparently they can't speak (?) yet they ARE capable of creating a nonexistent voice on a phone? Can they warp time and space?
