Sorry it's late, but my latest GuardianTelly Addict man-in-a-box is available to view. In it, I review the return of Dragons' Den on BBC2, C4′s The Secret Life Of Buildings (during which I refrain from accidentally pronouncing architecture critic Tom Dyckhoff's surname wrongly) and BBC1′s Saturday night special, John Bishop's Britain, which suffers from format fatigue. Have a look.
