Kate Garraway’s Life Stories (ITV) was built in her cheery image. Though Garraway started as a reporter, the Good Morning Britain star has spent most of her career in lifestyle TV rather than in hard-nosed journalism. So it was perhaps inevitable that her Life Stories debut should be altogether fluffier and sweeter than was the case with Morgan, who has left ITV for a new morning gig with Rupert Murdoch’s forthcoming talkTV startup.
