An excerpt from the ComixFan review:

Based on the story alone, Iron Man: House of M belongs next to Spider-Man: House of M as the mini which uses this reality�s premise most consistently and most interestingly. This is not a Doom or Hulk solo book or a New Avengers/Astonishing X-Men crossover. It�s a book about a racist society and the compromises and dilemmas faced by those trying to survive and/or destroy it. On the strength of his writing here as well as on Phoenix: Endsong Greg Pak deserves to be given a major ongoing title.
