I wouldn't worry about the any of the 'old fashioned' attitudes making it on to the screen, these days it will be woke as **** or just won't get made. I've read most of the first book and it's of course incredibly dated, so the on screen version especially in today's climate is going to be very different, I can't see anything like a faithfull adapatation as WOT is famed for its tedium as much as its length. So they're probably going to cvhange a hell of a lot and that might be no bad thing, it can't be as bad as the Shannarra Chronicles can it?
I hope its 'grim dark' as someone alluded to earlier and not a teen-centric 'relationships and feels' show, there's plenty of that on TV for those who enjoy vomiting profusely.
