Re: Ms. Marvel - SPOILERS
Captain America is a different situation because they went with Bucky which had a tie to it. If they had put some bad guy in the suit and then had him become Captain America and the focus on the comic I'd be WTF? about that too.
The 80s were great. Captain America kept wigging out and slaughtering mobs of people. They knew how to replace Captain America back then and keep it interesting
