This movie is about a couple, Claire and Paul, who go to visit her relatives outback (it's an Australian movie) somewhere. In the course of their visit, the grandmother, who is very old and ill, tells Claire that she doesn't have much time remaining and entrusts her with a valuable urn. Claire doesn't want to hear such talk but the grandmother continues and tells her we all gotta go sometime (this is true folks) -but that she wasn't worried because "the lady of sorrows" -she who bawls for the dead (actually, they more poetically used "wails" but being a wise-ass I couldn't resist) -would oversee her final journey. As well, she tells Claire that no one should harm the bawling lady (there I go again) or interfere. At this point you can guess what happens: one of them unwittingly did something to the bawling woman and unhappy consequences follow.
This movie, in my ever so humble opinion, is overall not a bad movie. The creepiest part unfortunately happens in the first quarter or so of it. So what went wrong after that? "Flying skeletons". Say what???. You heard me, folks. Someone had the bright idea of injecting FLYING SKELETONS in this thing. The effect of this was to make the movie seem a little silly, a little retro, and a little cheap, and therefore to negate or offset a lot of the genuine creepiness it began with. Folks (I think you will agree with me), there is no way in the world flying skeletons are going to freak anyone out; not in this day and age. These days, this is something that you would put in a horror comedy which this was not intended to be.
Notwithstanding the above, this is generally not a bad movie. It just lost it's way to further real supernatural creepiness in the early go with the introduction of the skeletons and became more of a "monster" or "creature" movie, of sorts, even though they were supposed to be ghosts. So while much was lost if you wanted to be supernaturally creeped out, there was still creature horror and suspense. And in additional defense of what was not a bad effort, let me say that there are some movies that are today considered cult horror classics that had skeletons in them that looked no better than these, but at least they had the good sense not to make them airborne.
