This issue essentially validated the Giant Size series as a whole, which had been rather lumbering and disjointed. Long after Hickman's run is over, and you can read it in its entirety, this series will be important(that TO virus being is foreboding). That said, it's clear that Hickman just isn't that into Ororo, even if this issue is well constructed. It is also clear that Dauterman loves her deeply, and as an artist showcase, this was a masterpiece.
I did enjoy the issue overall, particularly with smarty pants Monet coming up with the plan, but even with the esoteric feat(controlling the artificial World environment), Ororo was the least interesting character in it. As I suspected from his past work, he just doesn't really like her vibe. I'll give him some credit for being professional enough to recognize her importance to the franchise and do what he can to fold her in, but it is what it is.
I still look forward to XoS's world building. Hickman is a great writer, even if he's not really a Storm fan.
