She has a remarkable intolerance for most television, but reserves a particular contempt for badly made documentaries. In a former life she used to write, direct and present factual TV which makes her something of an expert on the subject.
As I have come to realise.
Strange then, that her intolerance of flakey documentaries is matched only by her phenomenal tolerance for populist crap. Which is how come I know exactly who won X Factor, American Idol and that ice skating malarkey, for the first time in my life.
And how come I have just spent the evening blubbing like a loon with Stray as we watched this amazing young man win Britain's Got Talent.
Bet you cried too, didn't you?
