As a showdown between arguably the 2 leaders in the Avengers, this movie doesn't disappoint (as I thought BvS did). You have many scenes that illustrate both sides of this conflict, the lawful and the rightful. Captain America and Iron Man are not opposite personalities. They just have different definitions of justice and protecting the world. The movie refuses to pick a side: it will push the viewers to pick one purely on emotion.

As a solo movie and a sequel of "Winter Soldier", this movie continues to have a "spy" feeling. It's not an epic showdown a la Avengers, it's more of a personal film focused in both Captain America and Iron Man. There's several twists of that kind. The action doesn't disappoint, however, the villain is forgettable.

As a Marvel Movie, this maybe the best one yet. It loosely follows the comics but I think it made the right changes almost every time. It has an incredible number of characters and yet it almost never feels overcrowded (Amazing Spider Man 2, Avengers 2) and it never feels like it has less substance than visual appealing (BvS). Every character is used correctly, and you can almost feel inside a comic book (Also, Spidey was very good)

Greaat job, Marvel. And also the Russo brothers. Avengers 3 is in good hands.
