Lots of networks are serving up 20^th anniversary specials noting the 1997 death of Princess Diana. This being ABC, it’s the only one able to present lengthy excerpts from one of her last and most famous interviews, with Martin Bashir – whose updated report is part of this ABC special, which, while taking time to provide a longer perspective, focuses in depth on the princess’ final 100 days. Terry Wrong, behind so many of ABC’s exemplary medical documentary series, is one of the executive producers here. For a full review, see David Hinckley’s All Along the Watchtower.
