Several murders in the San Francisco area follow the same pattern as the killings in the erotic novels of a steamy blonde author (Sharon Stone) who lures a police detective (Michael Douglas) on the case who may be in way too deep for his own good. Basic Instinct is a sleek, often dumb, occasionally intelligent thriller whose many sex scenes are as often unappealing as they are provocative. Stone delivers a soundly confident performance, Douglas' is a mixed bag as he seems to struggle with the heated scenes, and every story angle or scene spotlighting Jeanne Tripplehorn is completely awful. Paul Verhoeven's film attempts to channel classic San Fran movies such as Vertigo and Bullitt, and does so successfully, and then offers a conclusion that is supposed to end things on an ambiguous note, that comes off as more idiotic than anything.
