Finally the Masterwork title lives up its name here. Most of the X-men stories before this laid some solid groundwork, but are for the most part Marvel's version of the Doom Patrol, and rudimentary in that Silver Age way. Both early X-men and Doom Patrol had much to owe to Arnold Drake and Don Heck basic talents.
Here the Silver Age X-men are transformed into the Modern Age X-men by Roy Thomas and Neal Adams. Both Thomas and Adams have received more praise and recognition from other works, but it's these X-men stories that work best for me. This volume collects the end of the original X-men stories. The series continued on for some 30-some issues as reprints until the All New All Different Uncanny X-men kicked off the huge X-men phenomenon some years later, which was helmed by editor Thomas.
Man, reading these stories again... they still feel new and they are better most of the X-titles currently in print. I'd love to see Thomas and Adams team up again to pick up where they left off at the end of this collection.
