Dreamgirls

Admittedly a bit formulaic (three young African American women with talent form a group for fun only to be taken over by a manager who eventually comes to dominate them and put their dreams at risk), Dreamgirls has (1) a terrific cast and (2) incredible music.  If you are not moving to the soundtrack as you munch on your favorite movie food, you either need hearing aids or a sense of rhythm, or both.
