I mean, what even is this? I've been reading most of the series involved in this massive, cosmic crossover (All-New X-Men, Guardians of the Galaxy, Captain Marvel, some others I don't read), and none of them built up to this event AT ALL. It comes completely out of nowhere. Additionally, this event ended just two months before Secret Wars started, and therefore feels totally shoehorned into the Marvel timeline. Plus, at one point Beast is granted cosmic powers he DEFINITELY does not have in the other myriad of Marvel titles he appears in concurrently, so this event feels extra disconnected from the Marvel Universe. 
 OK, so here's the completely out of nowhere setup: a billion years ago, an advanced civilization was given a big, scary mirror called The Black Vortex that grants all who "submit" to it cosmic power. It, of course, corrupted them all and tore their civilization to shreds. 
 Cut to now, where J'Son of Spartax (Peter Quill AKA Star-Lord's dad) has gotten his hands on The Black Vortex and used it to power up some of his cronies. He wants to use it to power up himself and a bunch more of his cronies, but luckily he just stands around TALKING about how he wants to use it, rather than using it, so Star-Lord and Kitty Pryde show up and steal it from him. 
 Here begins the parade of nonsense. Every issue in this 13-part story deals with one or more of our heroes (and there are about 90 of our heroes) debating whether or not they should harness the power of something called THE BLACK VORTEX. What do you think you should do, dummies?! It's called THE BLACK VORTEX! It's not called the Gentle Embrace of Peace! Obviously it's going to corrupt you! 
 And yet, we get to watch these idiots (which include most of the X-Men, all of the Guardians, Nova, some Kree, Captain Marvel, God knows how many more people) constantly hem and haw about whether or not to use it. It's so dumb and, furthermore, so boring. How is every issue about this in a 13-part series?! There are some fights and some explosions and some cosmic insanity, but genuinely every single issue involves, at least at some point, a character debating whether or not The Black Vortex should be utilized for good. 
 Then, once some of them do start using it, the rules of The Black Vortex aren't even clear! It instantly corrupts some people. It doesn't corrupt others. Several characters end up "submitting" to it (which, to me, is another thing that REEKS of badness; you never "submit" to something cool and fun), with mixed results. By the end, so many people have submitted to it that, when one character offers to submit to it as some sort of sacrifice, I was like "Yeah, join the club." It's not much of a sacrifice if EVERYONE ELSE DID IT. But, I guess the story had to end somehow. 
 This story really makes no sense. It's repetitive, hacky, ill-defined, and unnecessary. With all of these series just a month or so from ending due to Secret Wars, I don't even understand what Marvel hoped to gain from it. It's not like it was going to draw new readers to series that were basically done anyway. And as an added bonus, since this story is told sequentially, good luck reading the little bits and pieces of it that are spread around the various collections of All-New X-Men, Captain Marvel, etc. Those issues will make absolutely no sense without the context of the full crossover event. 
 I don't get any of it! Ahhh!
