THIS is an American adaptation of a best-selling novel based on the life of its Fleet Street columnist author Allison Pearson.

A better title for it would be “I Don’t Know Why They Made It”.

Sarah Jessica Parker plays Kate, working in a Boston finance house, wife to aspiring architect Richard (Greg Kinnear) and mother of two.

Kate lives a life ruled by home and office to-do lists, her mobile phone and a powerful ambition.

The firm sends her to other cities at a moment’s notice. Her family tolerates her frenetic pace because she brings in money while Richard pitches for major commissions.

Kate may be a financial whiz-kid, but she’s blind to how she’s depriving her family of emotional sustenance.

The film isn’t really funny. It’s not romantic despite second billing going to Pierce Brosnan as Jack, a divorced colleague with whom she is pitching a new financial product in another city. Jack’s too decent a guy to come heavily on to her.

And I suspect he’s too wise to get involved with a woman whose relationship track record does not impress.

What entertainment values are in a film about such a professional high-flyer so unaware of her life’s realities? Discuss. Or dismiss as unworthy of serious consideration.
