First of all this one-shot continues in X-Men #12. That was disappointing since I like on-shots to be complete. Well, they good thing is that the story is interesting and bring new dimension to the Mutant battle for survival with a very unlikely powerful allied.
The writing is good but the art is amateurish in some areas. The reason is that there are two set of artists working in this issue. I prefer the team working on the "Now" as oppose to the "Then" team.
Otherwise this is entertaining and passes my standard for a need-to-be-read- story.
