I think that for its time this was pretty amazing. Looking back, perhaps not so much so. John Byrne's art is great, even if my tastes have changed, giving details to bodies that set a new standard for comic art. The story itself is about a group of mutant superheroes and villains that struggle against each other and to protect/conquer the world. Specifically it deals with the increasing power of Jean Grey/Marvel Girl/Phoenix/Dark Phoenix until the point that she is a threat to all life and how those who love her will fight to protect her despite what she might do. Interestingly, Dark Phoenix takes up very little of this collection; it is the events that help to initiate the dark power in Jean that are truly important. As such I really enjoyed the manipulation that the hypnotist, Mastermind, pulled and feel that such indirect actions are something more comics should consider. As for the whole "how do we stop Dark Phoenix?!" I didn't really care that much about it. It happened too fast and such high stakes as the sudden destruction of our galaxy doesn't seem as real to me as the subtle stab of a knife in the gut. I'd like to think that Claremont was pressured into short changing a story he wished to expand upon, if only I didn't read a decade worth of his comics and realized he was just kind of making things up as he went (akin to modern failures like Lost and Pretty little Liars among so many other sopa opera stories).
