8.55AM, FOXTEL PREMIERE Tina Fey and Amy Poehler have been two of the funniest people in the world for some time. Putting them together in a film makes perfect sense. But this ladies-party-hard affair rarely plays to the considerable strengths of its two stars. Little of note has been tried here aside from reversing the casting polarity of Baby Mama. Which means this time around, Fey is the slob and Poehler is the (relatively) straight one.
