Basically, if you like Downton Abbey, you will like this movie. Two of the main cast members are shared between the two productions, but their roles are switched. One is the aristocrat and the other is not.
More than anything, this movie was good, clean, wholesome fun. It is very pleasant to go to a movie these days that is guaranteed to be clean, where you don't need to worry about what your kids are going to see. Though the Cinderella story has been done and redone many times over, this is probably one of the best adaptations, and is definitely worth seeing.
