I'm basically tired of wallowing ,reticent, mopey anti-heroes, and on the flip side, crazy comic relief heroes. Basically a character being "Cool" or "bad ass" isn't enough of a reason for me to like them.
Captain America is my favorite character because Steve Rogers had EVERY reason to be a dark reticent character like Punisher, or Wolverine, but instead he has the inner courage to face hardship and presevere; that makes him admirable.
I constantly hear Cap being put down for being a jigonistic boring hero, but truth be told he has just as much, if not more depth than cool anti-heroes like Deadpool, The Punisher, and Wolverine. He stands for actual things going on in our society and is a good role model. Captain America is everything that America should actually be, and that is more powerful and resonant to me in my adult years than some anti-hero crusade.
