in sitcoms, comedies in general, where the general idea is “everyone is awful and it’s hilarious”, women being awful and hilarious is important. it’s also very important that that awfulness is not directed at or focused on their gender. i can’t remember every episode off the top of my head, but the handling of writing elaine as a terrible person never seemed focused on the fact that she’s a woman, or pulling from that.
adding more women would help, but yeah. having the woman be the stick in the mud who goes “ohhhhhh you boyyyyyys” is way worse. doesn’t give them any lines, doesn’t give them anything to do. you can still write a woman who’s the straight character of the comedy group but 1. it’s a common trend and one i’d tend to avoid where i can 2. you can still give that woman funny lines.
like i’d put it this way. elaine is funny. marge simpson, who is the straight character among the group often in simpsons, is also funny.
gamora, who was the straight character in guardians of the galaxy, got almost zero lines and in a movie i didn’t think was all that funny to begin with, got some of the worst comedy among ‘em.
it’s important that women get the same breadth of personalities in media that men do. and i mean breadth - if all the women are horrible, you notice a trend. just like how if all the women are the sticks in the mud… you get what i mean.
elaine being horrible in seinfeld works not just because she gets a full personality, good, funny lines and scenes, but also because she’s not the only woman that shows up in the show, and her personality isn’t transplanted on every other woman either.
