Where the Wild Things Are 2009

The 21st Century's Most Acclaimed Films list serves as a companion to the They Shoot Pictures, Don't They? 1,000 Greatest Films of all time list which, - by its nature - tends to have very few films from the 21st century in it. The 21st Century's Most Acclaimed Films list attempts to highlight and honour this century's most critically revered films and act as a sort of 'resting bay' for many great films that are likely to be included in the 1,000 Greatest Films list sooner or later.
