It's like Wanted Down Under but in other places. At the end the family are filmed phoning their loved ones back at home to inform them of their decision.
I saw one a few weeks ago where a woman's mum was sat on her own waiting for the call which then came from her daughter to say the whole family were moving thousands of miles away. The grandmother had been taking care of her grandchildren every day for a long time and you could see her fighting back tears while she put on a brave " I am so pleased for you" front in front of the cameras.
What's wrong with breaking the news face to face back home without the cameras? It just seems unnecessarily cruel.
