Recent college grad Annie Braddock (Scarlett Johansson) is all set for a career in business when she quite literally falls into a position as nanny for the four-year-old son (Nicholas Art) of a snooty, self-absorbed Upper East Side socialite named Alexandra X, played by a sadly miscast Laura Linney (among many of the movie's wearisomely cutesy touches is not giving a surname to the family that hires her).
Based on the novel by Emma McLaughlin and Nicola Kraus, "The Nanny Diaries" is, unfortunately, every bit as predictable and trite as its simpleminded premise would lead one to expect. Beyond trafficking in just about every stereotype and cliché imaginable - the heartless, neurotic, slave-driving elitists; the sensitive knight-in-shining armor love interest (Chris Evans); the nagging, free-living best friend; the lecherous, nanny-chasing husband (Paul Giamatti) - the movie is woefully unsuccessful even at treading that fine line between cleverness and cuteness that can make or break a film of this type. There is an affectionate tribute to "Mary Poppins" that - early on at least - suggests that the movie might actually try to do something a little daring, a little different. But that air of fanciful creativity is quickly squelched in favor of formulaic storytelling and cookie cutter characterizations.
Interestingly, the filmmakers, for all their championing of the women employed as nannies, seem to have almost as low an opinion of the profession itself as do the elite snobs who appear on screen.
All told, Johansson is really the only decent thing about "The Nanny Diaries" (well, little Nicholas Art is pretty cool too), but even her staunchest admirers would be well advised to look the other way when it comes to this film.
