Captain America: Winter Soldier-official trailer

The new trailer for Captain America; Winter Soldier has arrived. First impressions? It seems very interesting. As a comic book guy I know who and what the Winter Soldier is. But it is surprising that the trailer focuses so little on that aspect of the film. This could be good or bad, but mostly good as the trailer focuses on the tone for the film more than story. So, what is the tone? This movie seems a bit darker, but no less lighthearted. From what I gather from the trailer; it puts Captain America's old school ideology juxtaposed with America today. A line in the trailer is from Cap: This isn't freedom, it's fear. as he says this to Nick Fury while watching new Stealth Planes(?) being gathered and stocked up. Personally this aspect seems like a great idea. I think it worked in Man of Steel but I think people don't see it that way. Will they see it with Captain America: Winter Soldier? Only time will tell. Now, the trailer for your viewing pleasure.
