for the self irony of Dietrich performance. for the nice story and air of far age of cinema. for inspired cast. and, sure, for the respect for recipes of romantic comedy. it is not a link from chain of fashion of art. few sparkles, a seductive Dietrich, mixture of love balloons and fine humor, the dramatic small slice and the touching solutions to create identity in a ocean of clones, all is good reason to see it and, in a measure or other, to love it. because it is almost magic like many films from that period. because the acting is smart and the game of nuances not uninspired. because, after war of blockbusters, this film has the gift to be comfortable. and for occasion to travel in time. and discover than life is beautiful.
