Nothing special about 9 1/2 months. I saw it on the Lifetime Channel and I'm not sure how it ever made it to the big screen. There's very little chemistry between Grant and Moore. Grant's character seems quite inept at working through his emotions about being a dad. A good child psychologist would probably have some idea about his feelings for fatherhood. And he'd have collegues he could turn to.
Oh and did I mention the jokes are forced and not all that that funny? Well, the movie isn't hillarious. I like Hugh Grant in many movies...but this isn't one them. If you like romantic comedies or moives about pregnancy you might enjoy this. Otherwise skip it.
