The closest comic I can think of to this book tonally would be the classic Giffen/DeMatteis/Maguire run on Justice League. I loved that book, and I love this one too!
It has the same mixture of humour and adventure that Justice League did, without falling into the trap that that book occasionally did of lapsing into slapstick. This issue has a lot of stuff going on (financial worries for the school, microscopic students fighting Brood infections etc.) but Jason Aaron manages to handle it all with a lightness of touch that comes as a welcome surprise. The first two books I read from the stack this week were this and Punisher Max, two definite five star books that could not have been more different but both of them absolutely kicked my ass!
Speaking of ass-kicking, all the kudos on this book can’t just go to Jason Aaron- artist Nick Bradshaw is doing an exceptional job here, and his classic, Art Adams influenced style seems to be the perfect fit for the fun superhero tone Aaron is pushing. Between Bradshaw and Bachalo, this book is one of the best looking things out there right now.
In short, if I could only have one X-book in my life, Wolverine and the X-Men would be it! Awesome!
