The dance scenes are really interesting and good. The story is terrible. The acting is non-existant.
Leonard Maltin/Plot synopsis:
How to turn a rock video into a feature film--with glitzy images, high energy, an arresting music score (principally by Giorgio Moroder), and the stupidest story this side of Busby Berkeley. Still, this concoction about a girl with the perfect fantasy life (macho welder by day, sexy dancer by night, courted by the rich and handsome boss, watched over by a patron-saint ballerina) was a smash. Title song won an Oscar.
