I'll probably regret this, but the Mantlo-version of Alpha Flight is nearly impossible to reconcile with the Byrne-version of Alpha Flight. Unfortunately, the Mantlo era lasted a whole lot longer than the Byrne era, and during the Mantlo period, the foundation of Alpha Flight was undermined.
Not destroyed, which may have been better...undermined. Completely.
Correct me if I'm wrong, but it's taken years to get the team/comic back to near what it was.
And, no offense intended, others besides Claremont and Byrne have been able to do it [Chaos War: Alpha Flight through volume 4). Now, if a story/storyline can hold and build a readership as it goes on----
