Fresh and Familiar
I've never been a huge fan of Gillen's work, his writing coming off as a little pretentious to me. However, Iron Man's character fitting that quota to a certain degree, this story doesn't suffer much from this. However, there isn't too much innovation to be had here; this is a pretty basic Iron Man offering, which isn't entirely a bad thing, but doesn't allow it to stand out much.
The biggest draw to this portion of Iron Man's legend is that each issue covers a different, interesting, and unique suit, taking some cues from Iron Man 3, which happened to come out at the same time. Also presented in this manner is that Extremis' creator has just died, and Iron Man must clean up the mess, with Pepper Potts along for the ride in a strictly supportive role, again creating ties to the film universe. Beyond that, however, Gillen delves into Iron Man's rogues gallery for some interesting encounters that haven't been seen for a while, as well as touching on one familiar face. And the art is great, drawn by the same guy who did Ultimate Fantastic Four, Greg Land. And, while this does result in a lot of sexualization of every female in the series, it is a great style that works, especially for this character.
Ultimately, I feel similarly to this as I do to the Indestructible Hulk; for every step forward, there's a step backwards, resulting in a consistently good series that doesn't take risks and give readers what they want to see for the most part. So, if you don't mind this safe approach, you should be absolutely pleased as punch with what's offered here.
