1. The Character Relationships are Perfect
This movie legitimately feels like a real fight between friends. If you’ve ever been angry with a close friend, scenes in this film will hit uncomfortably close to home.
They act like real people. Steve is headstrong, and doesn’t do a good job explaining himself, and Tony is unwilling to hear him out. Hmm, that sounds like a number of real arguments I’ve had. They fight like people who really don’t want to be fighting. It makes the film work so damn well when you see these characters pulling punches for the sake of their friendship. And this is a film about friendships, both between Steve and Tony and Steve and Bucky.
These characters have been built throughout years of films to the point where they feel realized in ways that aren’t possible for a movie like TOM.
The key is patience. Marvel spent years of carefully crafted films to get to this point. They were incredibly patient, and didn’t try to rush anything before its time (Except maybe Iron Man 2; that one feels a bit rushed). And because of that, their track record has been incredible.
I’d go so far as to say that Marvel has yet to make an outright bad movie. They’ve made mediocre movies, sure. They’ve made movies that weren’t great, yeah. But “bad� Not yet. And if they continue to make note perfect, well paced and written, enjoyable movies with wonderful character work, they won’t make one any time soon.
