Captain America: The Winter Soldier follows the Nazi-stomping romp with a melancholy-tinged Bourne-style revival of the “don’t trust anybody” 70s political thriller. Probably the least light-hearted of the Marvel movies so far, which is an interesting way to go. Still has some stomping in it of course.
And it may cause some issues for Agents of S.H.I.E.L.D. season two.
And it has a mid credits scene and an end credits scene.
And the lack of billing for Black Widow in the title really does seem like an oversight.
And for the TWH audience specifically - Jenny Agutter returns.
