Bruce Willis fumes and fusses as Russ, a tight-assed workaholic image consultant who on the cusp of his 40th birthday comes face to face with himself at age eight (Spencer Breslin). Naturally the tyke shakes up Russ's strictly ordered life like an underage Spirit of Christmas Past. This child-empowerment comedy in the spirit of Disney's Freaky Friday and The Parent Trap almost works: the slick Willis and the tubby Breslin are a funny juxtaposition, and the supporting cast is first-rate, namely Lily Tomlin as Russ's deadpan assistant and Emily Mortimer as a gamine colleague. The film's undoing rests with director Jon Turteltaub (Instinct), whose touch is anvil-light, and screenwriter Audrey Wells (Guinevere), who chokes on the film's fantasy twists. This Kid exposes more than just the vulnerability of men: it lays bare a complete disregard for subtlety.
