Saw the midnight showing, and I believe they nailed it. Outstanding, fun film that managed to integrate Cap's history in a believable way while also carrying forward the shared movie universe in a manner that was natural and not forced. But the main thing that put this movie over the top for me was the human element. The presentation had alot of heart to it, and that's only fitting for a Captain America movie.
Overall, I think it's the best Marvel studios has put out since the first Iron Man film.
