Mary Pols's Accidentally on Purpose made me laugh, cry, and relate. I rooted for the 39-year-old film critic and her baby daddy, Matt, as I read the author's witty account of her unplanned journey into motherhood. Considering the book to be the mama of all pregnancy must reads, I even gifted it to several expecting friends. So last night, I sat on my couch crossing my fingers that CBS's new sitcom based on the text would live up to my expectations. It didn't even come close. Here's why.

• I couldn't wrap my mind around Jenna Elfman as Billie — I kept seeing Dharma and her over-the-top antics, but no Greg.
• Twenty-one minutes passed before I laughed.

For the rest of my observations, read more.

• The stereotypical characters on the small screen lacked the depth of those in the text. Billie is a haphazard cougar on the prowl and Zack (Jon Foster) is an overgrown kid with poor pickup lines and idiot friends, a big stretch from the endearing 20-something in the book that got a woman several years his senior in the sack.
• The season premiere was rushed. In a single episode, we saw the demise of Billie's relationship with James (Grant Show), her rebound fling with Zach, the two move in together and a nursery concocted.

I won't be watching the show again . . . unless the network saves the one-dimensional sitcom by hiring Pols as head writer. What's your opinion?
