You know what would be cool for the Captain America movie? Instead of the thirty minutes of useless origin story that can drag down every superhero movie, just start with him already the Legend of WW2.

Yeah. Dream on. EVERY superhero movie introducing a character (i.e., not a sequel) must start with a laboriously told origin story. It's a rule. Apparently. (The X-Men movies escaped this rule through a technicality--nobody has an "origin" per se except Wolverine. They're all just born that way. Not much to tell.)

I agree with you completely about how it ought to be done. But I don't think it'll happen.
