If you’re an X-Men fan thinking about following the “Trial Of Jean Grey” crossover from All New X-Men through to Guardians of the Galaxy, please be aware that this is all you’ll really see of them in Guardians Of The Galaxy #11.NOW.
This issue basically sets up the Guardians’ involvement in the crossover, showing events from their perspective leading up to their appearance on the final page of All-New X-Men #22.NOW. The final page here duplicates that, but from the Guardians’ point of view. The X-Men also get a little cover action and the occasional small historical hologram of Jean Grey, but that’s about it.
There’s also the matter of Marvel and their marketing gimmicks. I gave them a bit of a pass with the big #1 on the X-Men issue because it was technically the first issue of that story arc, but if it’s a true crossover than this is the second installment in the “Trial of Jean Grey.” Why should this get a #1 too? Are you going to tell me it’s a different style crossover than say maybe “Vendetta” in the X-Force books? I’m running out of excuses for you Marvel.
I’m not recommending you avoid this issue like the plague or anything though. Bendis is one of the best and busiest writers out there now, and makes this issue a good bit of fun. He’s self aware and self referential here, both using and subverting tropes. It might be worth it to check out The Guardians of The Galaxy, that is part of why they do these things, but if you’re just in it for the X-Men, then that’s all you really need to know.
