What they got right: After three issues of little happening, I finally have something to really talk about. (Granted, some action over the other three issues would have been nice.) Tony decision at the end I can get behind, but I would need an entire article to explain my reasoning. The ending is satisfactory as far as this story goes. At least Doom's reasoning makes more sense than a Bendis-written Doom.
What they got wrong: Am I the only one who thinks they overstuffed this to make up for the lack of anything substantive in the previous issues? As a result, Tony's decision admittedly felt a little forced. Also, if there are further stories written in this continuity (which is separate from the other universes, since they haven't bothered to just call it a "Marvel Adventures" title), it's disappointing to see that his supporting cast has been taken out, with Pepper and Rhodey pretty much "written out" (thankfully not dead, like other Marvel characters these days).
Recommendation: Still mostly for an Iron Man completist, and only to see the Tony Stark we all know in love in action again besides the Movie version.
