I think it’s also very important that this is a fight in which the characters *actually interact with their environment* in a way that feels real. Like, yes, have superpowers but there’s no cartoon physics involved, no obvious sense that this was filmed on an empty set with a greenscreen and the background was added later, or that they’re filming without even the people they’re fighting being present, just ‘look over here and make a hand gesture’.
The shield gets stuck in a car, there’s that awful moment of the knife sliding along the side of the van that cues up with the mounting tension in the soundtrack. Bucky’s arm impacts the pavement and actually dents it, etc. They’re jumping over/behind the cars and getting thrown into them/into the pavement in a way that feels more visceral than just ‘whoosh there was a wire & we CGI’d in the rest’. t has a sense of real world space to it, and that adds to the feeling of real world stakes.
