“Accidentally on Purpose’’ (CBS)
Kooky sitcom

Stars: Jenna Elfman, Grant Show, Jon Foster

The concept: After her boss boyfriend (Show) rejects her, a 30-something movie critic (Elfman) gets pregnant from a one-night stand with a younger guy. She keeps the baby, and the boy toy.

Our take: This is “Knocked Up’’ stuck in a flat sitcom milieu and layered with male older-woman fantasy. It’s predictable, cutesy, and ridden with clichéd age jokes.

Alternate name: “Dharma & Preg’’

Grade: C (Sept. 21)

From left: Jenna Elfman as Billie and Jon Foster as Zack.
