Well, I agree with the posters who have said things about price. Ms. Marvel was $2.99 for a year before the price went up. I think new readers would be more willing to try different books if they didn't cost so much. $5 for a single issue, even for a first issue, is atrocious.
Though, if I had my way, I would bring back richard rider in an All-New All Different Nova title where's he's flying around exploring space. I've got nothing against Sam, but I'm just not interested in him.
