On the one hand, I really am liking the feel of the movie. Cap taking on SHIELD corruption is a fantastic premise and really builds on some of the issues left hanging from the Avengers movie. I love the new uniform and the inclusion of both Black Widow and Falcon (though this does beg the question of where Hawkeye is). And speaking of Falcon, I was impressed with what little we saw of the wings in action.
On the other hand, there really wasn't much of the Winter Soldier in this. Granted, this is a first trailer and I imagine as the release date gets closer, we'll see more of him in action. All the same, as a fan of Bucky and the entire Winter Soldier story, I was left really wanting more.
A great looking trailer, all in all.
