all these programmes are the same??

Just watching the British version of this,there is an American one and a French one which is not on UK tv(I am British.)
Hate to say it that the Australian staff often seem more professional than the British ones.
I can't stop watching these things but they often disappoint,it would be great to see one set in North Korea or Russia but I guess this will never happen.
Would love to see someone argue with a Russian border guard?
