A Simple Favor: Simple it's not

Stephanie (Anna Kendrick) and Emily (Blake Lively) are two suburban moms who bond over extra dry martinis in this delightfully diverting mystery/thriller/comedy, which also takes a nod to sociology by examining an unlikely 21st-century friendship.

Not only do cool chick and nerd gal click glasses in friendship, one is a working mom, the other stays at home.

And they said it couldn't be done.

But is this a friendship? Is Stephanie really a goody two shoes? And what's with Emily? As one character put it, and the Movie Slut paraphrases: Never did such a beautiful women want to be so invisible.

As the plot twists and turns in unlikely ways, it seems this flick might also be a soap opera satire. Still, it's the acting chops of Kendrick and Lively that elevates it to must-see status.
