I think the whole "Avengers ambassador to aliens" idea they pushed with Carol was interesting and had merit; it was a fairly unique niche nobody else was filling, she was well suited to the role.....it could've been pretty great and given Carol a position to call her own. But finding the balance between "earth' and "cosmic" is something Marvel has often struggled with. It seems Marvel has given up on the space-based Alpha Flight and Carol running the show (last I knew anyway, like I said I'm behind on the book), and given how the book was at the time I can understand why, but I hope they revisit the idea and give it another shot sometime; it wasn't the concept that was bad, it was the writing.
As an aside, I recently introduced my seven year old daughter to Avengers: Earth's Mightiest Heroes. She spent all of season 1 asking when Captain Marvel (her favorite hero) would show up, and has spent season 2 bitching about her being called "Ms."
Well the Nova Corps are just Green Lanterns without the ring, always have been. But I don't know if I'd say DnA were just doing a GLC riff (beyond what Nova is to begin with); that book, especially in the first year or two, felt far more "sci fi with just a dash of superhero" than anything I've seen from the Lanterns.I agree, DnA's Nova was good - even if was basically Green Lantern in the Marvel universe (but then, Rich's origin is a copy of Hal's too).
I still don't understand why Marvel replaced Richard just as his profile was rising and the Nova IP was gaining some notoriety. But I've seen what Nova discussions can do to a thread so I'll take that commentary where it belongs before I start a fire here.
