SyFy has a brilliant piece about the feminism in Captain Marvel and how her antagonists’ tactics recapitulate anti-feminist tropes. What makes Captain Marvel bad? She’s too emotional:

Carol, like so many women, is told repeatedly throughout the film that she must “fight fair.” And “fair,” in the case of the men she encounters both human and alien, means “void of emotion.” … [W]e’re led to believe that detachment is necessary for any Kree warrior. … Nobility, honor, these are the things that matter most. That might be true, but it’s also a guise for a more sinister reality, one in which a man in power tries to stifle the abilities of a woman by equating her emotions with something negative, something shameful.

There are very minor spoilers, but I doubt, as vague and/or peripheral as they are, that they would actually ruin anyone’s enjoyment of the movie. So I recommend that everyone read the piece. Following Jessica Toomer on general principles isn’t a bad idea either.
