About Walker, though...
I would love to hear from people who never read about Walker in the comics. I am NOT one of those people, and have been actively trying to only watch the character in front of me on TV without the rest influencing things, but it's tough. Having said that...
His country asked him to be the new Cap. Is there a higher honour? Even if he himself legit wondered if he is good enough, he has the people in charge saying "YOU are our choice!" So, he serves. And it means a lot to him. It's also a HUGE burden to live up to, and the pressure would be enormous, it seems to me. Fortunately, he has his BFF alongside him to help.
Then, he has the opportunity to work with the 2 people who were the closest to the original Cap, and they make their distaste for him clear...even before he has a chance to really do anything to justify it. Imagine being Walker there, trying to impress the best friends of the legend you are trying to live up to, and them just not having it, and not really giving you a chance.
Then imagine getting your ass kicked all the time (losing more in the first episodes than Rogers ever did?). Then, the one person in the field who believed in you as Cap is murdered.
Anyway, I am really just curious about the POV from those who didn't read those comics back in the day.
