I saw this one years ago and it was a nice discovery.
This is a pure film. All built on its characters and storytelling development.
It's a B movie from Australia - which makes me happier, this is a country that I used to live in - that has nothing but a good story to tell and a good acting.
All set in basically three or four locations in which the art direction and the cinematography took the best out of them, transforming the loneliness and the emptiness of the places in a excellent element of the film.
The editing is very intelligent, always helping the twists of the movie getting more intense and also giving that motion and never letting the tension down.
Bottom line, it's a "old-time-kind-of-movie" in which no rush is seen and things happen when it has to happen.
8/10.
