When you ask anyone who followed the Infinity event and its side Avengers stories to fruition what might have been missing, the answer will come in one word: characterization.
Thus, Avengers World #1 where writers Jonathan Hickman and (mainly) Nick Spencer play Gardner Fox (or, if you will, Len Wein) by breaking the mega-team into smaller squads in order to give us a number of adventures and bring us some sterling characterization with some unsuspected characters.
Lesson learned: Excitement and adventure can come with characters acting like themselves.
Not a lot of setup in this #1; I guess Infinity and the Hickman Avengers have accomplished that.
No, the star of this show is the beautiful and highly-detailed work of the master of team comics, Stefano Caselli. Even the great King Kirby sometimes had one hero looking like the other, and Rich Buckler was the worst during his FF run. Here, everyone has their own face, their own character, their own expressions and the voice accompanying the art by Spencer is right-on.
I look for Avengers World to be a great character supplement to the plot-driven Avengers. This World is off to a great start!
