    I can understand completely that it wasn't many people's cup of tea. Certainly not a cosy feel-good movie for the growing sixtysomething demographic that presumably ensured finance for the movie to be made. But it your relationship is resilient – or you are single – there is pleasure to be had in this grown-up story.

    Yes, it was painful to watch at times, but delightful at others – a bit like life. Yes you wanted to smack them both for being so... annoying. No, you probably wouldn't invite them round to dinner without a certain amount of sighing. But I defy you to work out, before the end, whether they themselves would work out before the end. And I trust it will make a star, at last, of the luminous Lindsey Duncan.
