I don't mind that the celebrities aren't A or B-listers. Sometimes someone I've never heard of ends up becoming one of my favourites, though it hasn't happened this series.
My problem is the stunt casting - the gimmicky guests who we are supposed to be fascinated by, but they're all a big non-event.
I love this show, but I won't lie, I almost stopped watching after a few days of Anthony Mundine and Danny Green. Then the brits were inoffensive but totally underwhelming, and now the Oldfields just seem to be yet another unnecessary serving of bad taste.
At the moment the only ones sustaining my interest are Peter and Fiona.
