The finale of Season 1 of Titan's 11th Doctor. It's a bit weaker than its predecessors, in large part because it has to close the story of ARC and the Entity, and that was always a kind of weirdly abstract plot, so the finale is kind of weirdly abstract too. Which is a darned pity, because it brings down a Cyberman story. 
 Still, there's lots to like in this volume. The crew members are still fun. There's quite a lot of great writing. And the lead story, "Four Dimensions" is superb for its unusual storytelling and its great blending of the story with art. And, of course we get the finish of this initial story.
