There's a line at the end of Black Panther that I haven't been able to get out of my head in the weeks since I first saw the film. At the risk of being too spoiler-y (you will all complain anyway) I'll remove the context, but it goes something like this: "Bury me in the ocean with my ancestors who jumped from ships, because they knew death was better than bondage."
It's a powerful moment, one that's tragic and beautiful all the same. This is the moment when Marvel, for the first time, finally transcended the superhero genre. Never has a line in a Marvel movie carried this much weight; it's an idea reserved for great literature or essays, for something much bigger than a Hollywood tentpole.
