The great shame is that this mess belongs to director Amy Heckerling, whose gentle touch made "Fast Times at Ridgemont High" so much more than a teen sex comedy.

The opening scenes of Johnny Dangerously are so funny you just don't see how they can keep it up. And you're right: They can't. But they make a real try.

Keaton in starring role helps, but overall average laughs.

Good spoof of The Roaring Twenties
