Self-help on the big screen (again)

According to Vulture, Reese Witherspoon is going to star in a fictionalized movie adaptation of Men Are From Mars, Women Are From Venus. I'm frankly amazed that What To Expect When You're Expecting made enough money to encourage still more self-help-book-inspired movies, but I guess things could be worse. I mean, they could be making a rom-com about the Atkins diet. Or (shudder) The Surrendered Wife.
