Like Quicksilver, this book exists for little reason than to be dreary and somber.
Most of the mutants lost their power as a result of House of M. The X-Men respond by making the X-Mansion a mutant reservation, and are attacked by the Sapien League. The new government agency ONE responds by sending human-piloted Sentinels to man the perimeter of the X-Mansion. Begrudgingly, the X-Men accept. Then, in the last two issues, Polaris and Havok go on a road trip and meet one of Doop’s relatives.
I enjoyed seeing Chris Claremont bring back Trish Tilby, who was Beast’s girlfriend forever ago, but most of this book is pointless continuity building. Peter Milligan was great on X-Statix, but he just seems to be going through the motions. Same for artist Salvador Larocca.
