I also liked the "Nuff Said" issue. As I said, Morrison usually did strong work with Quietly, for whatever reason.
There was one aspect of Morrison's other arcs that I liked. I thought it was interesting how he brought counter-culture attitudes into the X-world, making mutanthood a hip trendy kind of thing(prompting new threats). The whole "everyone hates us" angle had been long overdone. It was fitting(if not groundbreaking) for the civil-rights movement era of the '60's, but it had reached it's limit in terms of producing good storylines.
Unfortunately, Morrison really got away from all that later on with the Weapon X stuff. Infact, nearly everything he had established early on as an interesting plot twist was lost by the time he moved on, proving once again that Marvel simply isn't in the market for change. I don't want to ruin it for anyone who hasn't read it yet, but Xorn's revealed identity was a huge setback, and strongly exemplifies what I'm talking about.
