I agree with that point, but I do also agree that the way many presenters behave detracts from the aim of the interview, or what the aim should be. It's meant to be about eliciting information, scrutinising claims, analysing and probing, holding to account. Too often it's about the presenter grandstanding, playing gotcha, engaging in stupid little games to try and put one over on someone, like a 10 year old arguing.
I suppose it's to be expected that many presenters are narcissistic, especially those who have a show branded with their name, but I would really like to see a lot more real analysis and challenge of actual ideas, rather than the look-at-me Billy Big Bollocks nonsense.
