As Captain America: The Winter Soldier celebrates its 10th anniversary this month, it’s time to take a quick examination of why the Captain America film is considered one of the best films of the Marvel Cinematic Universe (MCU).

Very few MCU fans expected much from the sequel to Captain America: The First Avenger, especially given that Joe and Anthony Russo, the directors of Captain America: The Winter Soldier were relative unknowns whose biggest accomplishments to date were directing episodes of Community. Yet, the film blew away audiences, critics and fans with its non-stop action, intriguing script and well-developed characters. It turned out to be one of the most important films in the MCU as it forever changed it.

Captain America: The Winter Soldier centers around Captain America/Steve Rogers (Chris Evans) uncovering a huge conspiracy in S.H.I.E.L.D. the spy organization he works for while grappling with a deadly ghost from his past. The first Captain America film dealt with Steve’s adventures as a superhero during World War II and ended with him being frozen in ice then revived during modern times. Ordinarily, a sequel film would have focused on fish-out-of-water tropes as Steve struggled to adapt to a whole new world. While this does happen in Captain America: The Winter Soldier, the film to its credit doesn’t concentrate on this concept. Instead it forces Steve to adhere to his honorable values as the world around him exhibits dubious morality. He clashes with his superiors who think nothing of spying on civilians and eroding their privacy with a clandestine project. He soon learns that S.H.I.E.L.D. has been compromised by the evil Hydra organization which plans to use the project to unleash a preemptive attack on its enemies throughout the world, including members of the superhero team, the Avengers. For his troubles, Steve is branded a traitor and chased by the mysterious Winter Soldier (Sebastian Stan), a deadly assassin who turns out to be his best friend Bucky from his World War II days.

All these plot elements successfully evoked a paranoid spy/political thriller that was highlighted with high-octane action scenes that demonstrated how vicious and lethal the Winter Soldier was. These battles were among the best action scenes ever seen in any film and has not been replicated in other MCU films. There was a genuine sense of danger and fear as Steve and his allies fought the Winter Soldier and the compromised S.H.I.E.L.D. agents. One scene in particular, which took place in an elevator, proved what a badass Captain America was. He was surrounded in a cramp space by several men who tried to arrest him and he singlehandedly fought and defeated them despite the odds.

But getting back to the political angle, the film always kept you guessing as to who could be trusted, or what was actually happening in a way that was not confusing and kept audiences engaged. It helped that the film featured Robert Redford as Alexander Pierce, a government official who was actually a Hydra agent. Redford’s acting prowess elevated the film and he was a great callback to the ’70s spy thrillers such as his own Three Days of the Condor.

More importantly, Captain America: The Winter Soldier was at its core a film about a man struggling with his past and his place in the world. In this situation, Steve tries to make sense of the new world he is forced to live in where it seems as if his values are out of step. But they are what is needed to fight a great evil that has corrupted the world and his best friend. What makes confronting Bucky so much worse for Steve is not only Bucky the lethal Winter Soldier, but due to brainwashing by Hydra over the decades, Bucky has lost his decent personality and no longer remembers his past or his friendship with Steve. The Winter Soldier is the only remaining link Steve has with his past and he has to find the strength to bring his friend back. His plight was very emotional and the sacrifice he made at the end to get through to Bucky was very powerful. The final battle between the two as Steve struggled to connect with Bucky was much more riveting than the wild, effects-laden action scenes involving Steve’s other friends fighting Hydra.

Captain America: The Winter Soldier propelled the narrative of the MCU from that point as it no longer had S.H.I.E.L.D. as the support organization for the Avengers and the world. This in turn would later have severe consequences during future Avengers films and immediately impacted the TV show, Agents of S.H.I.E.L.D. Even though that show is now ignored these days, back in 2014, it was clearly part of the MCU and the events of Captain America: The Winter Soldier directly affected the TV show as one of the main characters was revealed to be a Hydra agent, and the other characters underwent crises of faith. The film also led to Captain America becoming a man without a country and on the run as seen in the next Captain America film, Captain America: Civil War when his morality led to a devastating conflict with some of his fellow Avengers to the point that the team broke up and left Earth unprotected.

Thanks to Captain America: The Winter Soldier, the MCU began to be seen as something more than typical superhero films. This was reinforced later in the summer of 2014 with the release of the space epic Guardians of the Galaxy. Together, the films proved that the superhero film genre was very diverse in terms of storytelling and being able to surprise everyone with its potential. That is because not only is Captain America: The Winter Soldier the best superhero solo film of the MCU but one of the greatest films of all time.
