This is it!
Yes! What I've been waiting for: the meeting of the Scotts. If you read issue 3 you saw at the end that the young X-Men landed at the feet of Cyclops and his new team of mutants. Issue 4 picks up right at that point from the mind of modern Scott and what he thinks seeing Jean and himself. It was completely amazing to see what he felt, to see thought bubbles, which is great to see back, and to see him at conflict within and suddenly without. Bendis is doing some stellar work in this book and not a single issue has been weak since he began this book. Buy it fast!
As for art, the first few pages seemed sort of lacking which when saying that of Immonen is still amazing work, but then he did this neat splash page of all the faces of the mutants present in separate panels and it is just beautiful. The rest of the issue is yet again mind-boggling well done. I love the art and like before it continues to fit the mood of the book perfectly.
I can not say enough about this book. Buy it and love it!
