Mystique turned out to be pretty weak. For those looking for the ruthless assassin, don't expect to find her in this book. Also, Vaughn has an incredibly tough time handling his pop culture refrences in this book. With Mystique refusing to kill and a pretty damn uninteresting story, this is a book that doesn't deserve further attention.
However, Runaways still has potential. Vaughn just needs to watch himself on those pop-culture refreneces.
