This is one breezy film. Sinatra one lines himself solidly throughout. In films like this, there aren't many moments of reflection. This saves us the trouble of examining the plot and the character motivation too intently. The benefit to the viewer is that the whole experience remains visceral and on the surface. On occasion I like films that don't challenge me, that simply vibrate with a peculiar sort of corrupt, smarmy, highly heated decaying fun. Sinatra dashes all over Miami in search of his maguffin. He pops in to the lives of many marginalized denizens of the underworld. He gets a taste of the lives of the newly rich and partially famous. His alter-ego, Richard Conte, provides a mundane, safe balanced universe for him to rest up in from time to time but the bulk of his characters time is spent in high risk action and lots of smart-assed talk. And for this viewer, that was just fine.
