I've literally just closed this book after finishing the story, and felt compelled to share the joy this book brought me. I'm a long-time comic book collector and reader (over twenty years) who has strayed from the more recent developments in both the X-Men titles and the Spider-Man books. I ran across this book on clearance and thought it would be worth the price to see how Jason Aaron handled a team-up between the two characters. I was expecting some light reading and some good art. I was not expecting to have one of the most enjoyable comics reading experiences of the last couple of years, though. This book is amazing, and Aaron manages to tell a story that is both intriguing, funny, and moving. There came a point, in issue #5, where I so overcome with sheer comic joy that I had started recounting the story so far to my wife, complete with visual aids from the book itself. "And then Spider-Man did THIS!" Lord bless her, she met my ravings with an accepting smile. She knows that comics rarely get me so excited.
The more history you have with the Marvel Universe, the better, but it's not a requirement. This book is absolutely full of 80s and 90s Marvel references and asides that serve as easter eggs for those of us who have been reading these characters for a while. At the end of the day, this comic is FUN and is a joy to read. I'm so glad I ran across it. I knew of Jason Aaron from his independent work, but I had no idea how much he cared about these Marvel characters. It's something to behold.
