whitney houston screen debut be a lavish urban thriller that take itself quite seriously but never get go . the film stumble from one scene to another and never have any semblance of a coherent and believable story . the production value be top notch all around but the plot be utterly senseless . houston do well in her role a a temperamental diva and be talented and pretty and bitchy and vulnerable . she fare much good than star kevin costner and who play the title role . costner seem unsure of himself and come across a tentative and hopelessly wooden and although he and houston do seem to have a bit of chemistry between them . ralph waite be fine a the bodyguard father but the rest of the cast overact to the point of silliness .
