I didn’t like Captain America: The First Avenger (2011) much. However, Captain America: The Winter Soldier far exceeds its predecessor. This movie not only relies on Captain America’s super strength, but we see also excellent teamwork with Black Widow and Falcon. In this respect it is even better than The Avengers (2012), which spent a significant amount of time letting the superheroes fight among each other instead of moving the plot forward. As for plot, we get a more sophisticated plot this time, with so many things happening at SHIELD, this movie becomes a mandatory prerequisite for anyone wanting to watch The Avengers 2 (2015).
Note: this movie contains TWO extra scenes at the end.
