Of all the super heroes, Captain America is my favorite, he did it because "I don't like bullies". There wasn't a revenge motive, it was, simply he didn't like bullies. He didn't want to kill anyone, he wasn't trying to get even with anyone, he just plain didn't like bullies. The Winter Soldier' not only satisfies with its plentiful action scenes, it also offers some intriguing commentary on the current political and world climate, and turns out to be a sterling character piece. Scarlett Johansson's sassy, snarky Black Widow provides some of the film's best moments, delivering quips and back flips with equal panache. Marvel did an excellent job to let Chris Evans play the role of Captain, I mean whole thrilling action through out the movie, Only some actors can do that and Chris Evans is one of them.
