Rotten Tomatoes Score: 8% Why It Sucks: Falling far short of the inherent dramatic interest that a Princess Diana biopic musters up, Oliver Hirschbiegel's effort suffers from a hilariously awful script which transforms Diana's later years into a glorified Mills and Boon novel adaptation. The clunky romantic dialogue is more cringe-inducingly corny than affecting, and though Naomi Watts tries damn hard in the title role, she's ultimately helpless against the tide of outrageous awfulness sent her way (and she earned a Worst Actress Razzie nomination for her work on the film). Why It'll Become A Cult Classic: Diana may be a terrible film, but in a sense, that makes it infinitely more appealing to the many viewers who struggle with stuffy, baroque period flicks. For all of its problems, there is a sure accidental entertainment value to Diana, to laugh along with its terrible dialogue and revel in the abject failure of what was clearly marketed as Oscar bait. To see such a failure of intention fall flat on its face quite so horrifically is a rare feat in cinema, one that will ensure the movie won't be long-forgotten by audiences flocking to it until the end of time as a campy trash classic.
