You liked American Son? Frankly I found it a waste of time that it was just another case of Norman screwing with Peter and Harry, in the end all that's changed is that Harry is no longer rich.
I also thought it was dumb that this is the ONLY story in the current run to even refer to Dark Reign and the fact that Norman Osborn is ruler of the Earth by now. Really, that should've been a background thing as soon as it started.
I would've liked it more if it had a permanent MAJOR change to the MU: Harry accepts Norman's offer and becomes his Captain America on the Dark Avengers, while in secret Harry is working to undermine Norman's power from within. That way we get more of a gradual and surprising power struggle (Harry doing effective plotting?) in Dark Avengers than Moonstone screwing everyone.
