150 years into the future, the X-Men struggle to fight against Sublime, who now has control of the Phoenix, and is posed to take over the Earth and beyond.
Grant Morrison is a writer who's work can be hard to decipher at times. Especially at the beginning of his runs. He tends to go to a confusing and obtuse place, then at the end, iron out the details and hopefully make it all make sense. His X-Men run is the opposite. Because up until now, the stories have been fairly straightforward. It's almost like he needed to do at least one volume with the weird and indecipherable plot that he likes to do, before the final curtain call - because this last story, is pretty hard to understand.
It has to do with how bad things have gotten in the future if Cyclops walks away from the X-Men following the events of the last volume. So Phoenix has to fix this by erasing the future, and allowing Scott to change his mind (somehow) and continue the school and begin a real relationship with Emma.
The art is handled by Marc Silvestri, and to be honest, I don't think he was the best pick for this particular story. It looks very 90's and scratchy, and I think an artist with a cleaner style would've been better, as the plot is itself not very clear. The whole thing feels very 90's and that's because of the art solely.
While this volume is not the best to end on unfortunately, the run itself is still great in my opinion. They way Morrison came in and just really shook up the status quo of the X-Men was fantastic and a needed breath of fresh air. The look, the tone, the attitude of the book completely changes and is invigorated by his run. I think this is one of the greatest runs of the X-Men team, of all time. If you haven't read the entire run and you're an X fan, stop reading this and go read it!
