On the Dutch TV there's a program called "Ik vertrek" or "I Leave". It's about your everyday Dutch family deciding to pack up their things and leave to start a new life combined with a business or professional activity in another country. They give you an insight in the difficulties these people encounter (f.e. trying to start a camping-site in France without speaking French, getting mangled by the French bureaucracy etc.).
I do encounter these people now and then and their story is always the same. The film crew follows them for about a month in total, filming and sometimes directing the scenes that take place. The final, aired version of about 40 minutes gives systematically a negative view, highlights the things that go wrong rather than those who are a succes. Some episodes weren't aired simply because the emigrants came well prepared and nothing terrible happened. Drama sells, feel-good TV doesn't.
But I guess Barbara that one could combine success and failure in such a TV-program when the aim is to show what it really takes (predominantly as a person, but also in terms of good preparation) to start all over again outside your native country.
