Easily one of the best entries in the Marvel cinematic universe, The Winter Soldier is as much of a top-notch action thriller as it is a superhero blockbuster. It has a compelling premise, engaging story, and exciting action set pieces. If there are any real complaints, it's with the climax, where the action begins to go a little too over-the-top. However, even at its most bombastic, the Russo's always manage to keep the action in service to the story.
