There aren’t any characters in the best-selling pregnancy guidebook, unless you count hemorrhoids and sore nipples. But the movie version, which shares only a name with the book, is jammed with characters, many representing societal stereotypes of mothers. They include Too Old (Cameron Diaz), Too Desperate (Jennifer Lopez), Too Much Like Gisele (Brooklyn Decker) and Too Young (Anna Kendrick). Only Elizabeth Banks comes out of this mess with her dignity intact, which is remarkable considering that her character is a fertility-challenged woman who runs a store called the Breast Choice. The dads, including the louts played by Chris Rock and Dennis Quaid, aren’t any better. Of all the weirdly conceived, cash-grabbing cinematic projects of 2012 — and we’re talking about a year that spawned Battleship — WTEWYE took the cake.
