2 words: Oh dear.
Not sure why Bill Nighy would agree to do such a poorly scripted film.
Loads of mistakes throughout, including the boy checking the wrong leg before commenting how well the leg had healed ... it was a back leg not a front leg caught in the wire fencing, plus it didn't have a scratch on it, nor was the dingo limping when it was freed.
And that's just one example of this implausible rubbish.
Embarrassing to call it an example of an Aussie movie.
