‘I saw this amazing film,’ people used to say at dinner parties, ‘you must see it.’ And it was nice to have their recommendations; pleasant to trot off to see The Matrix or Four Weddings and a Funeral and be the one to rave about it at the next party. These days, just the words ‘You must see…’ fill my heart with dread because they are invariably followed by not a film, but a whole TV series, available in a box-set: The West Wing, The Killing, The Wire. Nothing makes the heart sink more at the start of a villa holiday than the sight of a fellow guest arriving with 30 episodes of Mad Men under his arm. Experience tells you that it is for these, not picturesque hilltop churches or the local trattoria’s funghi porcini, that the holiday will be remembered.
