I’m talking only of the Game of Thrones television show which I’ve been binge-watching recently. As far as I can tell, these “problems” are liberties taken by the show (I read all the books a while ago, so I may be wrong).
1. Ser Dontos, an overweight drunk, wears armor that has a marked resemblance to the American flag.
That’s just mean. He’s called Ser Dontos the Red, not Ser Dontos the Red, White, and Blue.
Though I’ll admit it’s kind of funny that he looks like a really crappy Captain America.
2. Catelyn Stark says “stand down” which is a phrase thought to have originated in the early 1900’s, and the Bastard of Bolton says “phantom limb” which is a phrase coined in the 1870’s.
Yeah, yeah—I know the show is set in a fictional fantasy world, and it wouldn’t really work to have them speak Middle English (no one would understand except English majors, and even then it’ll only be the handful of people who paid attention during their Chaucer class). However, I personally prefer medieval fantasy to avoid modern-ish technical phrases as much as possible. I’m really not sure if these phrases were in the books or if they’re only in the show. I’ll have to pay attention if I ever read the novels again.
