I have finished Ultimate Comics X-Men. Now just to finish up the last arc of Ultimates, then read Cataclysm and finish it off with the All New Ultimates or whatever the hell they call it.
So apparently when they said the X-Men who chose not to be cured of their powers were going to live on a reservation, they really meant it. They get their own sovereign nation in like a few square miles of irradiated dessert and have their American citizenship taken away. Nothing that interesting really happens. They develop magic seeds that can grow plants anywhere (like in their irradiated hellhole called home). Rogue becomes a crazy person who live in the trees and is like a shitty version of Poison Ivy. Psylocke mentally controls half of the X-Men to turn against the other and a rogue part of the government continues to try and kill all mutants. Naturally Kitty Pride saves everyone.
That leads us to the big conclusion of Ultimate X-Men (minus the Cataclysm stuff coming up).
World War X could have been interesting I guess, but there was sort of a pretty massive issue with the whole thing that they never really bothered to explain. Why was Jean Grey the villain? Brian Wood decided in the 21 issues he would be writing this book that it apparently doesn't matter enough to be explained. She rules Tian (a bunch of floating islands from an earlier Ultimates arc) and for some reason in her mind there can only be one city of mutants, so Kitty Pride and her group in Utopia need to join her or she will have to kill them.
They proceed to fight and have a war. Kitty Pride turns from Gandhi to Rambo in about 3 panels and also gains super strength to go along with her other powers. At least I assume so since she was punching the head off a bunch of robot/cyborg soldiers. Then in the end she blows up Tian with a mutant powered rail gun. Jean Grey then apparently gets to live with them in Utopia after agreeing to wear a power dampener and starts a garden.
The one redeeming aspect of this whole arc is that Kitty Pride goes on for issues that by fighting back she is going to be seen as a huge terrorist and everyone will hate her (she actually gives up control of Utopia to Colossus to prevent any blow back on the rest of them). After the war she meets with a representative of the Army who pretty much tells her no one in the United States government gives a fuck about the whole thing and they are just tired of dealing with the mutants. When she asks about the reaction to her blowing up Tian, she gets told the rest of Southeast Asia thought they were a bunch of assholes and are glad its gone.
Also on the plus side, at least in X-Men they call him President Rogers and not President Captain America.
I can really see why the Ultimate universe was put out to pasture. At this point, with the exception of 12 issues from Hickman and Spider-Man, there really hasn't been any good comics since Ultimatum ruined everything.
