Yes, I cringed at the casting, too, especially when, watching the trailer, I heard Parker deliver the narration in the same voice she used for Carrie in "Sex and the City." But Kate is funnier - less arch - than Carrie, and Parker reminds you what a dizzy, all-in, high-risk comic actress she can be when she's not too busy showing off the couture.

Amusing, but formulaic, romantic comedy.

Director Douglas McGrath's empathy rescues it from the brink of disaster porn - it's so good-hearted and optimistic that a swath of stressed out moms will feel the flick speaks directly to them, which it does.

Sarah Jessica Parker's myriad fans will doubtless appreciate her frazzled warmth in a part she energetically inhabits, but the picture at times feels out of step with contemporary reality and humorless in its adaptation of a comic bestseller.

She (Parker) looks exhausted, first scene to last, and that fatigue spills off the screen onto us.
