After an absence for several years, we're bringing back the Action category this time out, as series about spies, gladiators and a rogue nuclear sub provided plenty of exciting twists and turns. Meanwhile, there was plenty to love in the animation world, including a new incarnation of the Ninja Turtles and a kick ass sequel to Avatar: The Last Airbender. And when it came to sci-fi and horror, there was some terrific thrills and chills in the form of zombies, observers, Time Lords and more.
