First, we will answer the question in the title of the Russian version of the film. It is not difficult to be born into a royal family. If formally, if the princess is not only a position, but also a way of thinking, then the film does not give an answer to this question. Because the movie does not show an example of a serious change in thinking and growth over itself.
In general, the film is extremely naive and therefore interesting mainly only for those who in the fairy tale about Cinderella misses a piece about hard work and only dreams of losing a crystal shoe in front of the eyes of a beautiful young prince.
But Julie Andrews is good, aristocratic. Anne Hathaway, even in her early youth, knew how to make a funny face.
