Then ... I'm sorry, but these "new readers" are stupid.
I haven't read Heyer's novels, but I've read a lot of history and some books based on history, and it sounds like she's taken the right approach - indeed, the ONLY approach.
What's the
point of grafting modern attitudes onto her characters?
I looked up some of Heyer's books; it looks like they are set during the Regency period, which was obviously a very different time to the 21st (or 20th, or even mid-to-late-19th) centuries. After the end of the Regency (roughly 1830, IIRC?), England changed within a half-century - technologically, at least - to such an extent that the Prince Regent wouldn't have recognised it, and would probably have hated it.
But to come back to my point, I don't understand people who want characters from a historical period to have modern, 21st-century attitudes. Can anyone imagine a highborn Regency lady - or, for that matter, a middle-class Regency matron, or a lower-class Regency woman - being "feisty" or "plucky", or behaving like, or even looking anything like, say ... Katniss Everdeen (from "The Hunger Games") or Lisbeth Salander (from "The Girl with the Dragon Tattoo")? It's so dumb!
I won't even mention society's expectation of women during the Regency, or the fact that women's underwear as we know it has only existed since a period between WW1 and WW2 (so it's very out-of-place during the Regency), or that people's attitudes towards hygiene and food cleanliness was different, or that medicine was different ... or ... so many things!
I'm sorry, I know I shouldn't get so worked up. It's just ... this level of stupidity just infuriates me. People who think like this - i.e. that the past should be exactly like the present - are, at best, naive. At worst? Arrogant. "How dare the past be so different! How dare you for writing about the past as if it was so different!"
I wonder if people like this also expect a Crusading knight to have an M16. Or, perhaps, for two Tudor ladies to talk like this:
Tudor Lady #1: "Hey girlfriend! So what'd you think of dat new Shakespeare play, huh? Like,
totes boring, am I right?"
Tudor Lady #2: "You got it, babes. Like, plays are like,
so nerdy! Dat Shakespeare dude's off his rocker on da wacky-tobaccy!"
Please save us.
Anyway. The first sentence of L. P. Hartley's "The Go-Between" sums it up brilliantly: "The past is a foreign country; they do things differently there."
