Strictly speaking, Iron Man: Execute Program is the follow-up to Iron Man: The Inevitable. In reality, the Execute Program trade paperback, which collects issues 7-12 of the current Iron Man series, is the logical follow up to Iron Man Vol. 1: Extremis. While the Inevitable storyline that ran in Iron Man issues 1-6 came immediately after Extremis, it all but ignored those important events in favor of a more retro Iron Man tale. The Execute Program storyline is focused on the events that occurred during Extremis, and the consequences of those events.
In this storyline, someone is executing Tony Stark's enemies, and that someone looks disturbingly like Iron Man. Now that the Iron Man armor is inextricably linked to Tony Stark, Stark falls under suspicion of his Avengers teammates as well as Nick Fury of SHIELD. Iron Man hasn't been this hated since the Armor Wars.
Writers Daniel and Charlie Knauf deliver an Iron Man tale that is packed with action and intrigue, and one that successfully builds upon Warren Ellis's groundbreaking Extremis saga (go check it out if you haven't already). Their take on Tony Stark is what you always thought the character should act like. The billionaire playboy shtick has been replaced by the manic, obsessive, super genius inventor persona, which seems so much more appropriate to the man that created so many technological marvels. The Knaufs also set up tensions between Captain America and Iron Man that, combined with Stark's revelation at the end of the story, make a nice transition into Marvel's epic Civil War (Marvel Comics) saga.
While Adi Granov's brilliant painted artwork on Extremis has probably ruined Iron Man for all other artists, Patrick Zircher does an admirable job here. His style has progressed considerably since his last Iron Man project (Iron Man: the Iron Age), and is reminiscent of Steve McNiven and Trevor Hairsine's styles. I think his pencils could have benefited from a more prominent inker, but overall the book looks good. Plus, the painted covers by Granov are flat-out awesome.
Overall, Execute Program is another fine Iron Man adventure, and one that bridges the gap between two important Marvel events (Iron Man: Extremis and Civil War).
