I loved this movie and although it may have been slightly cliché, the dialog was quite smart and it was quite a funny movie. I think that if you expect the movie to be Oscar worthy, it will obviously fall short. But as it only attempts to be a sweet story about a misfit 15 year old turned princess, it completely lives up to it's potential. I think that Julie Andrews completely made the movie and that Anne Hathaway also did an excellent job. The movie is great for people of all ages because it has a simplistic plot yet has great one liners and great repartee between the characters of the Queen and Princess Mia. I also think that the minor characters are great also because they provide even more comic relief.
