It feels a bit elitist to get annoyed by the BBC making stuff you don’t like especially when it’s one of their most successful programmes and makes them in a fortune from the franchising around the world. Like it or not, some ‘low brow’ content like this actually makes the BBC money and gives them more cash to make the stuff you seem to desire but which has no commercial value.
I’m not sure can call the celebrities self-appointed, I quite often haven’t heard of them but they aren’t inviting themselves on and quite often my kids know the ones I don’t so maybe we need to accept that we are behind the times in the same way as when our parents moaned about the stuff we liked.
