Well, I like both of them, but Twilight is better. It has a great plot, romance (though I'd rather have another main couple but you can't change it of course) and fantasy (although the vampire sparkling is SO weird). Scooby-Doo is very good, especially the movies (also the real-life ones exept the latest ones), but it's all classic about demons, vampires and werewolves. That's why I like Twilight more.
