Sure, but he’s also the most interesting personality of the Avengers team. I’d have given him the most screen time too. I thought the Captain America movie was kind of dull. I liked Cap more here, but he’s still the least interesting of the main four heroes.
That's fine, but Iron Man has had three movies now to develop his character. I've had my fill of him. Captain America, on the other hand, has a lot more potential. His fish out of water, 21st century thing was played mostly for laughs in The Avengers but I'd like to see that idea explored in a standalone film where he gets himself up to speed.
Also, Avengers hints that Cap is starting to realizing that SHIELD may not share his core American values. It's actually the catalyst for him to stop trying to make the others comply with SHIELD and, instead, re-orients himself to the new team dynamic. I for one would like to see this idea explored. A Cap sequel should send Cap out to explore the new America to try to find his place in it. What an opportunity for internal struggle! Will his traditional American values be swallowed by the vapid pop culture of this future America? I'd also like to see more of the "tactical genius" I mentioned in previous posts. He needs to reassert his leadership skills in this age of high tech war. I think Captain America could be a really interesting character. More interesting than Iron Man, even.
