For the most part, the writing of these characters is pretty spot on. At this point, I have come to accept the fact that Scott truly believes that what he is doing is the right thing. The only real issue is both the writing and visual portrayal of Emma Frost. Long been known as more or less a sex icon, Emma is being written in a much more reserved and conservative fashion. Her dialogue doesn't quite fit, and her new look is hardly a representation of the White Queen. This may partially be due to her being knocked down a few pegs after losing her telepathy, but I would have expected at least a remnant of her former domineering personality to shine through.
When all is said and done, Uncanny X-Men #1 is certainly an intriguing tale. A mutant civil war is undoubtedly in the midst, and it will be interesting to see how relationships will be strained, alliances will be made, and loyalties will be tested. You may not like Scott Summers right now, but I can guarantee you that this opening issue of Uncanny X-Men is a pleasure to read.
