The Kilroy loops make the programme sound more sensationalist than it actually was. Generally the audience was full of people that had shared similar experiences alongside experts in that particular field. Kilroy's skill was remembering the stories of each of these people in the audience and referring to them throughout the programme.
Yes. It was in a different league to Kyle, and usually quite a bit less sensationalist than Vanessa and Trisha on ITV. The last ITV show of that format that was similar-ish in tone was 'The Time, The Place' (which was - if anything - higher brow?)
Kilroy was quite 'tabloid' for a BBC show - but did handle serious stuff pretty sensitively too.
