Making a single programme for (say) a costume drama costs around a million pounds. For the same budget, programmers can make an entire series of 'fly on the wall' documentaries. The public have tired of airports, hotels, restaurant kitchens, police teams, customs staff, etc, so the programme makers have looked for something new. It's just another phase!
By propaganda I basically mean the effect that most documentarys have; that of making aware an area but through doing so makes it inviting - in the case of an Army programme - to young men especially who seek for some excitement in their lives.
The bomb squad I find very interesting, especially that one man who voiced that it was just his job, he had to go on, although the fear took all sense of honour out of it.
Are they possibly making it look better than it is?
