I mean, do you want it to be perfectly accurate and feel inauthentic or be technically inaccurate but feel authentic?
You know the buildings weren't all white in ancient Rome, but if they were pink and blue in the movies and TV, it'd throw you the hell off.
Your statement was "to accurately depict how it was." What does feelings have to do with that?
With regards to the depiction of buildings in Rome, how do you know it would throw me the hell off? You have no idea how much I know about ancient Roman architecture, the sources and colors of marble they used, etc. I really do not think anyone would be surprised to see the Romans were not black and white in their color schemes.
However, I am also put off with the language in movie scripts today. I grew up on a fairly large farm working side-by-side with the hired help and cursing was pretty much reserved for special occasions (busted fingers, piece of equipment breaking down badly, etc) and the few people I knew that talked like a modern day movie character were not respected much at all. They were really kind of a novelty.
You know, watch a movie like
The Wild Bunch, one of my absolutely favorite Westerns. Sure, there is cursing, but nothing like what modern society has become. It was off-putting in
Yellowstone, but season four was so bad, that given the discussion of the dialogue, I'll not bother with
1883.
