This was a good issue. The tell tale sign is that I can't stop thinking about it. I knew Marvel was going to start playing with our heads in terms of the Skrull Invasion effecting past major events. I just didn't think it would be so tight.
This issue makes me want to go bakc and read every major Marvel book in my collection from the past 5 years.
With a major fucus on the House of M, this issue disects what the House of M looked like for the "sleeper" Skrulls that were already in place on Earth (in particular Yellowjacket and Spider-Woman.)
The ideas are complex. The planning is uncanny. And the results are an air tight issue of the Secret Invasion.
This would not be an easy issue for someone not familiar with past continuity and major events. But for me, it was perfect.
