I really liked on how they addressed the issue of people asking on why Steve or Tony didn't just call one of the other available Avengers for help.
It's definitely understandable and makes sense. Though I wish I could say the same about the finale in TDW, but I won't get into that here.
I also enjoy on how they have no problem really staying true to Steve's good old values.
I feel like there are times where filmmakers just opt towards creating more "anti" or even "reluctant" heroes because there's more flexibility in what they can do with them and all of the drama, but I don't think it's wrong or necessarily boring to present naturally good spirited heroes like Captain America, Superman, or Spider-Man.
