If you've watched anything on ABC in the past three months, you've probably seen the Once Upon a Time promo - the one that serves to entice viewers to tune in for the non-stop action the series has to offer with quick cuts and dramatic cymbals and drums. It follows the classic theme: the ultimate clash between good and evil. And during the March 11 episode of Once Upon a Time, ABC aired a Bachelor commercial that's a riff on their own aggressive marketing campaign: "Good vs. Courtney."
