Channel 4
Tulisa, Dappy and Fazer of North London pop phenomenon N-Dubz – or, if you prefer, Tula Constavlos, her cousin Dino Constavlos and their schoolfriend Richard Rawson – are easy to mock, and Channel 4 know it. The first episode of this showbiz slice-of-life documentary about the ebullient trio is so slathered with the kind of hideously knowing upper-middle-class arched-eybrow voiceover that characterises the whole of the channel's T4 youth programming strand that you have to wonder if they actually credit the viewer with the ability to form an opinion at all.
