I like Sam as Cap. I like Miles. I'm cool with the new Thor. I don't care as long as I like the stories. Comic fans will never stop grasping on to whatever they're familiar with so I don't even think a lot of the complaining is something these companies should care about
Also unpopular opinion I'll catch flack for but idc. I think a lot of straight white guys have a hard time understanding perspective. The average little kid doesn't wanna look up to ****ing war machine man. They wanna have a spider-man or a superman. Something they think matters. And no new character could ever reach that level because people don't support new books and characters.
