There are no fresh revelations in this feature-length documentary about Diana. What it does offers is a compressed view of her short life as the Princess of Wales, seen through archive footage and old interviews.
The effect is like a rush of fuzzy memories, given new shape by slick editing and the distance of time. It makes for compelling, if uncomfortable, viewing.
After opening with 25-year-old footage of paparazzi gathered outside The Ritz in Paris, director Ed Perkins rewinds, showing a teenage Diana making her way to her car as future ITN anchor Carol Barnes badgers her with questions about her rumoured engagement to the future king.
