Thanks to CrimsonKing, I was able to catch the sneak preview last night. One thing I was EXTREMELY satisfied with was the fact that the Russo brothers were not afraid of Cap's shield. I felt like they used it exceptionally well, and it was a HUGE improvement to the action elements of CA:WS. If you have felt that "Captain America's Mighty Shield" has been missing from the Marvel Cinematic Universe thus far, you will NOT be disappointed with CA:WS. I love the fact that they weren't afraid to really cut loose with it, and that they kept things feeling somewhat grounded while still playing loose with the physics of the shield. One of the many, MANY cool elements to the film!
