Screenwriter Nora Ephron has constructed an incisive tale that, despite its tendency toward whimsy and cuteness, manages to combine brilliant zingers with deep, lasting reflections on relationships. Director Rob Reiner encourages top-notch performances from his ideal cast. All four of the leads devour their meaty roles with aplomb, though Meg Ryan is a revelation; her winsome cheeriness and comic timing had never been highlighted so well. Carrie Fisher and Bruno Kirby, perpetual character actors, are given ample opportunities to shine and both do. The sappy ending is of a piece with Ephron's other work, but it's a small flaw in the grand scheme of this charming picture, set eloquently to the music of Harry Connick Jr. Kudos as well to cinematographer Barry Sonnenfeld, who offers a picturesque New York to make Gotham dwellers proud.
