Agreed that Captain America is the worst. No question.
I thought Fantastic Four had the strongest start. Avengers was initally decent, & Iron Man started out...ok. Then they all kind of fell apart as it became increasingly obvious that the Heroes Reborn Universe wasn't going to last...
I agree that Cap was the worst. I thought Iron Man started the best, had the best artwork and I liked the way they used Hulk. Wasn't it also the quickest book to lose its initial creative team? I think all four books were covered by fill-in artists before they finished 12 issues. Maybe the least necessary contribution was the extra 13th issue of each where they Amalgamed Marvel with Wildstorm for some reason.
