I can't imagine the Avengers minus Cap. It just ain't right. It's always been hard to like the character because he is kinda uptight and the equivalent of Superman as far as being the moral center. So...likeable, not really. Essential...well yeah.
You guys just don't know how to let go and have fun. They ain't all gonna be Citizen Kane
Upon reflection...the Avengers movie was meh across the board. What did ANYONE really do?
Plus, I thought Loki was really solid.
I'm hoping the next one takes a more focused approach and isn't just spectacle and "hey look everyone the avengers are on screen finally".
