It's a sad reflection on todays' society that want comfort and everything doing for them.
No, - it reflects the real object of these programmes. The BBC does not want to make a series about filming wildlife, just as in other series it did not want to make a series about trekking through the Andes, Africa etc.
These is banal reality-tv. The "competition" to become a wildlife director - or assistant to Alan Sugar or whatever - is irrelevant; the BBC just wants the drama, and so they choose candidates who will provide the drama.
It is reality tv - or soap - but one thing for is for sure - the stars won't be the animals, the plants or the landscape.
From the BBC blurb (see first post):
Judged by award-winning wildlife film-maker, James Honeyborne
I can well imagine that David Attenborough would have nothing to do with the series.
