Character death/return events are a staple of superhero comics. We all know them, we all groan at them, but we all read them because we kinda have to in order to understand what's going on in the given comic book universe. The thing is, they're some of the most unnecessary stories you can tell in the medium because at the end of the day, the character in question is just dead/alive again and that's all you really need to know. There is rarely a good reason or explanation for them to be dead or resurrected in the first place, more often than not it's some contrived bullshit that makes little to no sense.
Phoenix Resurrection: The Return of Jean Grey is no different. Something something happens with Phoenix, then poof and just like that — Jean is back. Back again. Which time is it? Who cares. The entire point of this book is in its title, and you don't need to know anything besides that fact because there is no logical explanation as to why she's back. Apparently, she's been in some hallucinatory egg the whole time, but when Old Man Logan goes inside to talk to her she just springs back out of it. That's it.
Matthew Rosenberg tries to pull something out of this setup by playing out some emotional scenes from Jean Grey's history towards the end, and kudos to him for that, that worked really well. The book is overall quite readable, and it has some interesting surreal scenes that are pretty intriguing until the big reveal nullifies all that. On the other hand, at five issues the book is really slow for what it ultimately achieves, and it would read much better at four or even three issues, but then Marvel wouldn't have gotten as much profit out of it.
Phoenix Resurrection features some gorgeous artwork from the likes of Leinil Yu, Carlos Pacheco, Joe Bennett and Ramon Rosanas, all top Marvel talent, so if there's one thing I can give this book it's that it looks beautiful. Every artist did their best to invoke some powerful imagery, from smaller character moments to big, fiery psychedelic scenes inside the egg.
Ultimately, the book is just not worth the time or the money. I'm sure that every important plot point from this series will be covered in some convenient expository dialogue later on in whatever comic this one affects down the line, and the main point of it is already spoiled by the title. Jean Grey is back, guys. Now let's hope Marvel does something interesting with her.
