“Captain America: The Winter Soldier” was the first of the four flicks to enter theaters, and it built high expectations with a smart script, strong acting and an abundance of beautifully executed action sequences. In short, the movie is a first-tier superhero picture that improves on the franchise’s already solid debut, “Captain America: The First Avenger.”  “The Winter Soldier” is set two years after events depicted in “The Avengers,” and Captain America, a.k.a. Steve Rogers (Chris Evans), is settling into life in the 21^st century.
