Compulsive viewing for me - a bunch of talentless over-inflated egos having to put their money where their mouth is - epic fail all round.
I particularly relish the Interviews at the end of the series, when the full extent of their bullshit is exposed 
What astonishes me is that these wankers have all (presumably) watched previous series, yet appear to have learned nothing at all and make the same basic errors over and over again!
(I think my favourite moment was a few years ago, one team was running a Pizza stall and decided that for Chicken Pizza's they needed one whole chicken per pizza.....fabulous)
