Re: Other things about the Winter Soldier we'd like to see?
The long hair? No.
In the comics, it felt like a self-aware joke. 90s comic had a trends of characters getting a grim and gritty adjustment, anti-heros with bionic arms,r long crazy hair, dressed in black leather.
And as Brubaker was taking one of Marvel's quainter, somewhat colorful and he turned him into an elite and remorseless assassin, so Brubaker went all the way.
A little longer, maybe, at least to display how Bucky has weathered through the years that Steve had slept through. But not Loki-levels of crazy hair.
