Forgot to say; the other thing I loved about the film was how sparse it was. For the majority of the movie it was just the two lead characters, and the Australian desert. And there was not all that much music to interfere with the normal sounds like leaves, sand, campfire, water. The two leads didn't even spend all that much time talking... which is a testament to both actors' talents in the physicality and reality of their characters.

It was like the landscape itself was the lead role, the driving force of the story of the film. Nice.
