What I'm hearing is some cool, updated world building/retconning that retains some of the original flavor while bringing some new and exciting concepts. The only thing I dislike (aside from the name thing but what're ya gonna do, y'know) is the new look of Cap. I prefer the old costume, maybe modernize his physical look by removing some of the Fred MacMurray-ness in his face. I don't like the crackling energy from his chest.
Mary will always remain a favorite.
