I'm wondering how anybody feels Dark Reign has measured up so far to Marvel's other recent "events". Is Dark Reign even really an event since there is no miniseries?

I think in the long run that Dark Reign has been pretty good. Unfortunately it has been mostly the stories that were going on in regular titles that made it good. I don't think that any of the Dark Reign: (Fill in the Blank) mini-series were really worth writing home about, even the one that I bought I only bought because of my desire to support the creative team.
