When she's on the screen, Brigette commands your attention just by being there, mock-pouting, prancing about in revealing drapery, merely pouting or casting knowing glances at whoever needs to be trapped by her charms.
The plot was the sort of thing that Doris Day films were based around, but here mixed with more farce, more energy, and less coy dialogue; there are farcical situations galore, and common sense does not apply--the viewer is either in the mood for amiable poses from a self-aware sex kitten, or not afraid of a rather convoluted plot that involves gangsters, a butler with a Buster Keaton attitude, a woman professor that claims the straying lead, or totally impromptu musical numbers that owe a good deal of filching from MGM in it's Minnelli years of glorified technicolor.
All of which to summarize: good fun with some hearty laughs and a major bonus in a young star just beginning to realize her considerable impact on viewers, a musical farce with a little romance twisted into a somewhat feeble plot.
