I'm not certain if this is the secret of Joss' success on TV, but what I like about his creations is that he takes a formula situation, and then turns it upside down. The cute little blond cheerleader, instead of being the monster's victim, is the thing that they fear the most, The blood sucking monster vampire becomes the hero, protecting the helpless. The futuristic space man becomes nothing more (or less, depending on your point of view) than a roaming cowboy with a space ship instead of a horse. Joss makes heroes out of victims, champions out of monsters, and uses outlandish, supernatural elements to make commentaries on everday life, morals, and human behavior,
