Query: Such a shame ...

It's already been said that the script was weak for this film. I concur. I believe Tina Fey and Amy Poehler, if not the best female comedians ever produced by SNL, they are most certainly among the top 4 or 5. That's why it's such a shame they didn't have a great script to help make this a great comedy. Sometimes mediocre acting can be elevated by a good script, but seldom can a poor script be saved by the actors, however good they may be.Tina Fey should never agree to take on another comedic role without serious control of the script - she's too good a writer to risk her career to a bummer like this one. And she and Poehler have such wonderful chemistry & splendid timing together, it's just a shame this movie wasn't what it might have been.
