Yeah, I actually really liked that ending for Cap more than I thought I would. In hindsight, I think it was better that Stark die, and Cap be the one to retire. Stark could really never retire as IM, because he’d always be a marked man. Cap was able to be the one to retire by giving him the ability to go back and live the life he was supposed to. Having them both die I think would have been a bit much. It had to be one or the other. I actually like that sort of passing of the mantle as well to the next CA, with Steve Rogers actually choosing his successor, rather than him dying and someone takes it upon themselves to fill his shoes. It feels more earned when it’s passed on by the true Cap.
Only thing I would have MAYBE done differently was have Steve actually meet Peggy at the Stork Club for their dance, as opposed to showing them in their house. Her sitting in the club, thinking he won’t show, and then he walks in to her surprise and she says her classic line of “You’re late.” To which he responds with something along the lines of, “Was busy saving the world.” To her, she’d presume he was referring to the events of TFA with taking down Schmidt’s ship, but the audience of course would know what he meant.
