I was just on youtube trying to find the movie theme. I'm not sure which one is right. There are a few that are very similar but slightly different.

The one consistent thing I found was that I couldn't find something clearly identifiable in the music.

DC's Batman vs Superman wasn't the best it could have been. But I watched it again at home one time just to pay attention to the music.
Batman, Superman and Wonder Woman all have clearly recognisable themes. For the most part... Batman's is a little less defined but maybe because the dream sequence didn't follow the patterns.

Essentially, they all have their own leitmotif that identifies them as they come on screen.

But when I listen to the Captain Marvel theme, I'm not sure she's got one in there.

I've heard some criticisms of the Marvel themes, but didn't pay attention.
Did each hero have a leitmotif in Infinity war, or any of the films? Does Marvel just not do that?
