Ashton Kutcher and Brittany Murphy are newlyweds who travel through Europe, veering from one culture-clash disaster to the next. The joke is that it's Kutcher who's the spoiled, bratty princess; he plays to the teen female peanut gallery by becoming adorably unglued in one cute predicament after the next. For a while, this portrait of a Gen-Y ''starter marriage'' is dumb fun, but it collapses into the most generic sort of teen movie-ville.
