The film is a spy thriller mixed with some aspects of "superheroness" and I think that's what makes this film one of the most respected and loved in the entire MCU. It puts CGI on the side and the Russo Brothers make it a hard hitting, action packed, spectacle. The addition of Black Widow and the relationship and chemistry between her and Steve Rogers is the cherry on top of the cake for me. It introduces Sam Wilson as Falcon who, even though he doesn't have any powers himself and doesn't fight aswell as both Black Widow and Captain America, doesn't feel out of place with just his wings! The winter soldier is a fantastic villain too!
