I'm reluctant to use the term "Anti-Twilight" because it has become such a cliche. It's the nature of pop culture phenomenons that we inevitably spend a few years comparing everything to them. The Hunger Games is the Anti-Twilight because Katniss is a good role model. True Blood is the Anti-Twilight because it has "real" (read: more traditional) vampires. Warm Bodies is the Anti-Twilight because it's...you know, good. But I can think of no other apt name to describe Beautiful Creatures, as "The Anti-Twilight" it what it has very intentionally set out to be in the same way that The Golden Compass set out to be the Anti-Narnia.
