Nicole Kidman's Grace Kelly biopic, Grace of Monaco, opened the Cannes Film Festival this week and is being savaged by critics. It currently has a 5 percent on Rotten Tomatoes. Sounds like it's so bad that it's a must-see.

In a few days, eternally-sad-seeming Nicole Kidman's new film is to open the Cannes film festival. In Grace of Monaco, she plays the sad-seeming-in-retrospect Grace Kelly, the movie star and eventual princess of Monaco. And the sadness is still contagious, apparently, now extending to the film's backers because it's been denounced by the Monégasque (it's a great word) royal family as a "farce."
