I just facepalmed about this “mewling quim blah blah Joss is a sexist moron” stuff myself so hard that I bruised myself. Seriously?
Warning: lots of opinions and Widow/Pepper/Hill love and Avengers movie spoilers.
Learn the word “joke.” Think about whether it could possibly apply to a writer saying that his greatest achievement in a film is inserting a piece of raunchy archaic vocabulary.
Think about how interesting and actually empowering that line was when seen in context. Loki mocks her in a sexist way for what he perceives as her innate lack of strength, which she was consciously faking (while possibly still showing some real emotional complexity and weakness which is not inherently sexist it is interesting writing) in order to manipulate him into telling her exactly what she wants to know. Loki is punished for those sexist thoughts, and Joss simply was able to find a creative and completely in-character way of expressing them. ”Shakespeare in the Park,” remember?
“Mewling quim” is a fucking fantastic insult from a screenwriting standpoint - horrible and uncomfortable and infuriating and Joss should be proud of coming up with something so viscerally affecting. I already knew what “quim” meant when I saw the movie, and when it came out of his mouth, my jaw dropped because it was really shocking. And horrifying. And cruel. You know why? Because Loki as a character is often shocking and horrifying and cruel. Joss wrote successfully for a character. Learn to separate character from writer.
