This movie is everything that Marvel should be. Let's start with the villain: Zemo. Phenomenal, he has a motive that makes sense, he is creative, uses his intelligence to fight the Avengers and not his strength, and is shown to us not through conflict but through small snippets of his plan throughout the film. The red herring plan is great and allows for the perfect conflict. Breaking the Avengers apart is the perfect concept for Marvel, it creates tension between characters that will have to be overcome in the future. We learn about Bucky, learn about Tony's past, and we get a massive insight into Steve's morals. Steve has already been seen doing what's right and just even if it disobeys direct orders, but this time he does it not against the government, but against his best friends as well. This movie also provides an introduction to multiple characters that were previously either not yet seen in the MCU, or had just not yet been introduced to the other characters. Overall it really is the emotion and story and development of Tony, Steve, and Bucky that drive this film to be as good as it is.
