Oh, what wacky sitcom-inspired situation has Katherine Heigl gotten herself into now? Seems, after the accidental death of her best friends, happy singleton Kath is forced to live in a big house and raise an orphaned baby with the help of a macho, self-absorbed jerk (Josh Duhamel) with whom she would never, ever, in a million years fall in love. ... Yeah, we're not buying it, honey. That's the same thing you said about Gerard Butler in The Ugly Truth. But if viewers are in the mood for a romantic comedy with lots of baby poop jokes, then this one is eager to fill the need.114 minutes PG-13.
