First five pages were shown in the preview.
The X-Men arrive at Port Washington to confront a Kirby-cracklin' omega mutant. Kitty orders Storm to fuck off and save civilians, which seems like a waste of a mutant who's so powerful she can make it rain on the sun and move the moon. Rachel gets knocked out immediately, which really highlights how this issue is a celebration of everything that sucks about Gold (especially if you take those preview pages of CW drama into account too).
Kitty gets the omega mutant, Brian Morrison, to calm down, but he immediately gets shot in the head by a vigilante citizen. Kitty gets furious because Brian didn't hurt anyone, but the good citizen points out he destroyed an entire neighbourhood. Kitty and Nightcrawler teleport the mutant to the hospital. The doctor in charge there refuses to operate on Brian because he's a dangerous mutant. Kitty accuses him of being a racist, but I'm pretty sure she could've just reminded him of his Hippocratic Oath.
Kitty then demands Rachel mind control the doctor into operating on him, which really shows how much Marc "I read every Kitty issue ever" Guggenheim knows about that character. Fun fact: Kitty was an ethics teacher back during the JGS days. Anyway, the rest of the X-Men turn on Kitty but it's not like this was properly set up (on purpose at least) in the previous 36 issues of misguided fanwank, nor will it be further explored because it's the FINAL ISSUE. Which brings me to an adjacent complaint that is shown in full force here and in every other issue. What characters has Kitty actually interacted with in Gold besides Colossus? Guggs mentions in the coda that what makes the X-Men great is their dynamics with each other, but Kitty had zero dynamics with any character except Guggs' author insert. It's stuff like that which only further excarbates the fact that this is a crappy solo book. But with at least some good dynamics other characters would've been spotlighted, and it could've shown us something new about the characters. Could you imagine how good that scene could've been if the book had been about Kitty becoming like Emma all along as she wrestles with the responsibilities she now carries? But lol it was just a dumb romance comic for 30 issues.
Anyway, conventiently another doctor shows up and is willing to operate on Brian because she was one of the bigots Kitty talked to in issue #1, but became convinced of the X-Men's heroism by watching The Fact Channel, because Guggenheim is Not Very Subtle. Now the GENIUSES at Marvel don't have Perez redraw that scene from issue #1, but are actually using Ardian Syaf art, a guy who was fired for wanting to kill all the Jews. That definitely won't help the fact that the X-Office ruined their two most prominent Jews recently.
The issue ends with the X-Men waiting in suspense if Brian will be alright or not. A group shot shows the original six Gold members, plus the replacement team. But not Rogue and Gambit, who got MARRIED in this book (I guess Guggs is still sore about that). Also it mentions that Gold is dedicated to Chris Claremont. I'm sure he'll be happy about that.
This book died the way it lived: by doing a one-shot issue about an extremely dangerous mutant worse than Bendis or Austen did. Guggs' attempt to get vaguely political falls flat on his face. None of the characters except Kitty do anything. Kitty is unlikable and OOC. The art was great.
At least Guggs admits in the coda that Gold was unoriginal nostalgia garbage. 2/10, worst run ever but the wedding issue was iconic.
The good news is that it's over.
