Spoiler Alert!
The scenery is great and for that it is worthwhile watching. I mean Tasmania - not your everyday filming spot. However, there are some holes in the plot. Others have pointed them out: how did the boy and girl survive and got out, for example. The biggest hole though is: the whole story and trauma hinges on the two young men who died trying to rescue the young boy. They were called, the girl said, she did. Now, they both were about to drown and were shook around in the stormy waves, in the water for quite a while. But as she reaches the rock, she can take out her phone and call the others? Give me a break!
