Good watch
This is a well written, well directed and well put together film.
Very good twist at the end although...
SPOILERS
I knew the old man, old woman and the mute girl were dead, before their reveal.
However, it does make for a good and intriguing viewing experience.
There was quite a bit of soft speaking which was at times hard to hear. Nicole Kidman did well, as did the rest of the cast.
Worth a watch.
