Can't quite put my finger on why this campaign sucks.

You can't blame the Butterfinger people, really. Like everybody else these days, Nestlé wants to grab some of that tasty Frat Boy demo that spends money with the combined forethought of a general invading Russia in the dead of Winter. But, well, you're a candy bar—and a candy bar with very strong ties to a 10-year-old. Wish ya luck and stuff, but to make your ads work, you'd need to use a different finger.
