While Tina Fey and Amy Poehler have the potential to become a funny screen duo, this movie wastes their talents, for the most part. Fey plays a single woman who wants a baby but cant have one. Shes got big bucks, so she pays a surrogate (Poehler) to carry her child. Poehler moves in with Fey, and hilarity is supposed to ensue. Small supporting performances from Greg Kinnear and an unbilled Steve Martin are OK, and the leads are likable. Its just that the material isnt up to snuff. Fey usually writes material shes involved in, and her touch is missing from this movie. Its just a series of pregnancy jokes that weve all heard before. Poehler can be very funny with good material, but grating when the material is less than fair. Needless to say, shes grating this time out.
