The best that this movie could possibly be called is mediocre. After having seen a real theater show of this musical, I found that the movie version wasn't nearly as good. To begin with, neither Jean Simmons nor Marlon Brando are very good singers, and as they have the biggest singing parts, they weren't very good choices. Another part that disappointed me about the movie is that four songs were taken out (I've Never Been in Love Before, My Time of Day, Marry The Man Today, and A Bushel and a Peck) and three songs were written for the movie (Adelaide, Pet Me Poppa, and A Woman in Love). Some parts of the story, such as the end, were changed quite a bit, and some were taken out altogether, probably to make it shorter. There are some good parts of the movie. Frank Sinatra and Vivian Blaine sung very well and added humor to the movie, and You're Rocking the Boat was very well done. I would recommend watching a stage version over the movie version, since it will probably be better.
