I was collecting X-Treme X-Men when it was in stores up to issue #16, when I quit comics entirely. I don't remember why, exactly, but I did. Well, I started up again a couple years ago and just recently bought this book- it's totally worth it. This book cashes in on the original mission of the X-Treme team, changed its purpose and, of course, concludes the orignal arc.
The story focuses on Rogue, not one of my favorites, but this issue encapsulates everything Rogue is about, at least for me. She is confident, a bit violent, unleashing her power- yet finding its limit. The art is Larocca at his best, combined with realistic, yet understated colors.
The only drawback to this book is you need to read the first 16 issues of X-Treme X-Men to get the full heft of it- I feel like the very greatest books are self-contained. However, all things considered, this book is closer to 5 stars than 4. All in all, a fantastic read.
