This seems to be a concept movie from a new studio/director. And so must be taken with a pinch of salt, it's not a 10 by a some way, but not a 1 either.
Story - there isn't one. The opening scene draws you in thinking oh what's happened, seems daft but let's see. But by the end I'm still scratching my head on what the story was. It has the old classic family member dies, let's move to a remote country house with no neighbours.
Acting - on the whole is mediocre, but the script can be blamed for that. Some really awful conversations between mother and daughter including one near the beginning. Mother asks daughter to look out for signs as she is driving. They are on a single track driveway to the property, your not going to be looking out for signs. This is just one example of a number of poorly written exchanges. But there are points where it improves sligtly.
Music - usuall suspense horror music, with the annoying tones when something is about to happen. But acceptable.
Overall - I'm not going to watch this one again, it's longer than it needs to be but there is some good concepts. Probably should be lower in my ratings but suggest giving it a go anyway.
