Really good watch, would watch again, and can recommend.
If you're into realistic horror/abduction, then this is a great one to add to your list.
This seems like a low budget Australian movie, but they use what they have very well. Most of the movie takes place in a little house out in the sticks, and its the cinematic shots that really make the movie as good as it is.
It's very hard to talk about without spoilers, but the movie builds a great atmosphere with weight to it.
Probably the worst thing it does is show the best friend character having a "normal" prom night that is almost completely unrelated to the horror movie. It really is a double helix rom-com -- survival-horror of a movie.
If you like "People Under the Stairs", "Don't Breathe", or any of the "Saw" movies, then you'd likely enjoy this.
