I would like to point out a few of the lessons taught by this book... Taught to me at least...

1.  Do not judge a story arc until it is concluded.
2.  Do not point out mis-characterization or plot holes until a story is concluded.
3.  Do not prejudge a character until the story has concluded.

I was going to write this book off, I told my brother that if this issue didn't click, we were done with the book.  We both felt underwhelmed by the last two issues and were fully expecting crap from this one.  Boy, were we wrong.  I won't get into an in depth analysis as I figure that this many still not be everyone's cup of tea, but for me, what makes this book is....

"Three words... You're Hank Pym"
The Scarlett Witch reveal.
Tying the creation of this team to the original Avengers.
Norman Osborn, and the general feeling of loose, but tangible interconnectedness in the marvel universe. 
"A god and a super solider is all the Avengers I need."

A fun fun book that I hope denotes where this series will go, and hopefully the first two issues were just warming up and getting things into place. If you picked up the other two (or even if you skipped them) and were hesitant about continuing, do yourself a favor and pick this up, I guarantee it will be tying into the greater picture.
