Not even the talents of Dolly Parton and James Woods can save the shaky premise of this Disney comedy with a Chicago setting, directed by Barnet Kellman from a script by Craig Bolotin and Patricia Resnick. Fired from a dance instructor job, Parton leaves her fiance and her small town for Chicago, where she accidentally winds up on the radio as a talk-show psychologist dispensing advice to callers; her show is such a runaway hit that Chicago Sun- Times reporter James Wood decides to investigate her credentials. This starts off brightly enough, but the fatal mistake of the filmmakers is to assume that the profound common sense and populist appeal of the heroine can be inferred from Parton’s natural charms rather than actually demonstrated. The movie never manages to paper over this gaping hole, but some agreeable secondary performancesby Griffin Dunne, Michael Madsen, Deirdre O’Connell, John Sayles, Spalding Gray, Jerry Orbach, and Philip Bosco, among othersprovide partial compensation.
