Years ago, Harry Enfield made the wonderful 'Norbert Smith: A Life', a mockumentary about the career of a fictional actor which allowed him to parody decades of British films. In 'The Love Box in Your Living Room', his focus is no disimilliar (this time, British television), but to his credit, he adds something new to the mix, as the programme is made in the style of Adam Curtis. Curtis's own (deadly serious) programmes combine striking images with consipatorial nudges to overlooked connections; and Enfield's takedown is assured and funny, while some of the commentary reminds me of Philomena Cunk. It's a little too high-concept to be utterly hillarious, but it's a worthwhile and quirky addition to the BBC's celebration of its own hundred-year history.
