Baby Boom is an atypical upwardly mobile 80s comedy that sadly over eggs (over fertilises?) the pudding by having not one, but two fish out of water situations; businesswoman becomes parental guardian in the film's most successful and sweetly funny first half, and heading out to the sticks and struggling to adapt and conform in the flagging second half.
So uneven is the two situations that it makes it feel like you're watching two different movies; the cinema equivalent of a cut and shut.
I'd give the first half three stars and the second half two at a push.
Still Diane Keaton can do this sort of thing with a winning charm in her sleep, but she's beaten in the utterly adorable stakes this time round by the baby of the title who has far less screen time after the first hour, again another reason why this sadly outstays its welcome.
Directed by Charles Shyler, a man whose entire catalogue of work seems to be a litany of missed opportunities and ill advised projects.
