Oh my! I'm not sure where to start, but I certainly won't give anything away. Captain America: Civil War picks up a year after Avengers: Age of Ultron after the destruction of Sokovia during the battle with Hydra. It sets up the premise similar to Batman v. Superman: Dawn of Justice where the government and citizens become fearful and distrustful of the superheroes who have promised to protect them. Except it does it better with characters we are familiar with and a few we are not (or not in these versions). The Avengers are asked to sign the Sokovia Accords after innocent people are killed in Lagos during an Avengers operation; Tony Stark/Iron Man (Robert Downey Jr.) thinks they should sign, as does Vision (Paul Bettany), Rhodey/War Machine (Don Cheadle), and sort of Natasha Romanoff/Black Widow (Scarlett Johansson). Steve Rogers/Captain America (Chris Evans) thinks the Avengers should maintain sovereignty, especially as the world seems to be after his childhood pal, Bucky Barnes/Winter Soldier (Sebastian Stan). Sam Wilson/Falcon (Anthony Mackie) stays with his pal; Wanda Maximoff/Scarlet Witch (Elizabeth Olsen) is on the fence, but probably because she suffers from guilt for her role in the Lagos disaster. A new face in this crazy collection of enhanced humans is T'Challa/Black Panther (Chadwick Boseman) who is more interested in vengeance for his father than picking sides at this point; and Scott Lang/Ant-Man (Paul Rudd), Clint Barton/Hawkeye (Jeremy Renner) join the party on Team Captain America and Peter Parker/Spider-Man (Tom Holland) is with Iron-Man. They have been turned against one another with the help of Helmut Zemo (Daniel Bruhl) who is looking for his own vengeance against the Avengers. There is a lot going on with a lot of heroes, but unlike X-Men: Days of Future Past where there were so many characters you didn't know where to look and they weren't all really included, or Batman v. Superman: Dawn of Justice where the new characters were included in 30 seconds spots almost as an after thought, the additions get enough screen time, dialog and action. The story is also paced in such a way that the dialog is used to explain the past and the present, and I didn't think it got bogged down in verbosity or preaching. It gave the audience time to breathe between action sequences and understand what was happening, and seamlessly moves us forward to the upcoming movies in the universe. I love the addition of Black Panther; I would have liked a little more of Vision and Scarlet Witch (I'm still mad they killed off Quicksilver). And without spoiling anything, I found myself enjoying Spider-Man more than I thought. I was skeptical, but Tom Holland really brings the smart-assery and fun of Spider-Man. The movie is on the long side, but honestly, I didn't mind. I worried a little because there were children in the audience and sometimes they don't sit so nicely (at least one couldn't read the subtitles, so mom had to do it - not cool), but for the most part, everyone was chill and just enjoying the movie. Wanda's accent comes and goes, and I only minded that a little bit. The action and the stunts were beyond awesome. What else can I tell you? I'm not sure you need to see it in 3D; you should be familiar with the previous movies; stay through the credits. Anything else, you'll have to see it yourself because I will not ruin it. Lastly, there should be an Oscar for stunt coordination or something like that.
