I don't disagree Rambling Rose, I used to watch chat shows but have gone off celebrity culture I too find them quite boring, although I do like Graham Norton I haven't watched him of late. Michael Parkinson certainly had a certain amount of gravitas compared with Jonathan Ross say who was prone to making all manner of lascivious, crass remarks to female guests, that was when he wasn't interrupting with anecdotes about his own domestic set up especially as regards to his dogs in particular. MP was undoubtedly far more professional and I did enjoy some of his interviews but I think there was a detectable amount of subliminal sexism going on when he interviewed younger female personalities. I hated the way Charlotte Church's emergence from childhood to teen years, when she was still so, so young, was put under scrutiny by the media per se, so I would have expected him to swerve that quite honestly. Who would want that time of their life picked over when like many of one's peer group, you are on a learning curve and sometimes lacking in sound judgement. I'm glad she's managed to build a life for herself away from the spotlight.
Chat shows are often a platform for guests to promote their new film, record, book, which I imagine is a contractual obligation rather than a pleasure as demonstrated by a sometimes sour faced actor or two. There have been guests on MP who have been really good raconteurs, aside from the wonderfully funny, Billy Connelly I would include Tom Hanks and the off the wall and sadly missed Robin Williams.
