This is a pretty miserable excuse for a crossover. By the end, I found myself so bored with its entire premise that I just rushed through the last few issues, trying to hurry everything along as quickly as possible. Even that didn't speed up this slow dud. 
 For starters, layering another time travel X-Men story on top of the already time-travel-heavy Bendis series just seems like an insane idea. I guess on some level it could be kind of meta or post-modern, or even comedic, but it isn't presented that way. Instead, we get a bunch of random X-Men from the future dropping in on the X-Men from the present, who are also still joined from the X-Men from the past as established in All-New X-Men. It's a real jumbled mess, and forces us to watch about 10,000 characters wax philosophical about time travel while we try desperately to remember who everyone is. 
 To me, though, the biggest, most unforgivable problem in this book is its refusal to explain why the X-Men from the future are even here. They repeat several times that "telling the present X-Men why they've arrived will do too much damage to the space-time continuum," but they TIME TRAVELED. Who cares about space-time at this point?? Tell us WHY we are watching this hodge podge of mutants do random stuff for 10 issues. By totally avoiding the characters' reasons for being here, we have absolutely no idea what to root for. This glaring storytelling error made for one of the most underwhelming, frustrating X-Men reads I've ever endured. 
 Genuinely, by the end of this book, you will not know what happened. It is a complete stall; a total waste of pages that just seems like Marvel was just killing time so each writer could get caught up on other stories or something. The action isn't even that thrilling, nor are the new takes on the future X-Men. I hate giving one star reviews, and I also hate only saying bad things about a given book, but I found basically nothing to like in this whole series. I wish a future me would come back in time and tell me not to read this.
