AS the incredibly glam cover of Vanity Fair demonstrates, 2008 was Tina Fey’s year. Her Saturday Night Live impersonations of a certain vice-presidential candidate ( along with a slew of Emmys) meant she had to leave the dinghy of cult comedians and board the luxury cruise ship of mainstream stars. So as well as long-time fans salivating to see her reunited with SNL costar Amy Poehler, there will be many people who watch Baby Mama to see what all the fuss is about. Unfortunately, they probably won’t be any closer to understanding because this is a pretty average movie. Not average as in ‘‘ synonym for not very good’’, but just average. There are laughs but the predictable plot is not the best vehicle for either of these talented women. Fey stars as Kate Holbrook, a driven executive at an organic food company who, being the wrong side of 35, decides to have a baby on her own. Unfortunately, her uterus has other ideas, so she hires white trash Angie Ostrowiski ( Poehler) as her surrogate. Hilarity, it goes without saying, ensues. Fey and Poehler have great comic timing and a fantastic chemistry with each other. They wring what they can out of the material. Steve Martin is also good value as Kate’s new age boss, and neurotic parents will identify with wanting to sterilise the ball pit. Unfortunately, Sigourney Weaver’s overly fertile surrogacy broker doesn’t pay off quite as well. Baby Mama is entirely watchable, but with the amount of talent involved, ‘‘ not bad’’ is not good enough.
