I liked this less than I expected to, honestly. Fall of the Mutants is the second big Marvel Crossover event, but, unlike Mutant Massacre, there's very little overlap in the stories, here. This is a crossover more in tone or theme than in action. X-Factor are dealing with the realization that Hodge might, in fact, be a bigot working against them. Shocking. Certainly nobody saw *that* coming. This also introduced Apocalypse and the Four Horseman, and gives Angel a pretty huge change. These are probably the strongest issues, by far.
The second section deals with the X-Men, who end up divided, following the Mutant Massacre. They believe that the Mauraders are still out to get them (which is true), so Storm heads out looking for Forge to get her powers back while Wolverine leads the remaining X-Men (Longshot and Dazzler, who join the team at some point off panel, Betsy Braddock, Rogue, Havok, and Madelyn Prior; Colossus is recovering from his paralysis, Kitty is slowly regaining her physical form, and Nightcrawler, sadly, is still in a coma). The X-Men issues mostly have them kind of wandering around a bit, getting to know each other, fighting the Mauraders again, and, eventually, setting out looking for Storm, before facing The Adversary. While these issues will directly lead to the X-Men ending up over in the Outback (probably my favorite era of X-Men?), reading these now feels a little disjointed. They're not bad, but the story isn't as tightly paced as the X-Factor issues, and the cast don't totally mesh during this arc. The disconnect between X-Factor and X-men feels especially weird during this arc; Havok and Cyclop's wife, Maddy, are bouncing around with the X-Men, Wolverine *thinks* Jean Grey might be back, having detected her scent a couple of times during the Fall of the Mutants, but none of the X-Men think to check in with X-Factor during that event or this one? It's a little weird. Overall, the X-Men section isn't bad, but the Storm/Adversary sections are *SO* verbose, and it feels very out of character how easily the Adversary is able to manipulate Storm to his ends (also, the kiss is weird...).
Lastly, the New Mutants end up disobeying Magneto and heading out to tackle the Ani-Mater (eye roll) who ends up having a connection to Hodge. These were, to me, some of the weakest issues. Maybe it's because I never grew up with the New Mutants, but I found the artwork extremely off-putting. These issues do connect more directly with the X-Factor issues in that Hodge shows up and the team has to stop him, which results in his apparent demise when his plane goes down, but the general arc here is pretty silly. Sam takes alien drugs and the team has to save him from being killed by aliens who are jealous that Lila Cheny is interested in him? Poor Doug gets killed in a spectacularly silly scene that is supposed to be dramatic, and then Magneto ends up looking like an actual lunatic, despite more or less being right.
The other tie-in issues are mostly bad. The Captain America and Hulk issues don't add anything to the arc, really. The Power Pack issue is fine, but, again, doesn't add anything. The Daredevil issue deals with the bedlam that breaks out in Hell's Kitchen as a result of the events in X-Factor, which is kind of neat, but, again, there's just not much direct connection to the larger story, so having it here feels like padding.
One thing that was kind of neat but that basically *never* comes back up again: this is probably the first and only time the X-Men and X-Factor are unambiguously seen as heroes by the larger world. X-Factor get a freaking *parade* through NYC, and the X-Men are followed around by an NPR reporter as they sacrifice their lives to save the world. Kind of a shame that the world basically immediately forgets that they were heroes, but such is the life of a mutant in the 616.
Recommended for serious fans of the classic X-Men. This is a HUGE tome (and, really, I think I'd have preferred whatever issues Longshot joined the team in, instead of the Cap, Hulk, Powerpack, and Daredevil issues).
