Outside of film restoration, old movies should be enjoyed the way they were made.
The notes they could read in the movie credits about it being a colorized version simply told them that all of the colors in that movie had been added later.
I was so convincing that one of them interrupted his teacher in class to let her know she was wrong about the rainbows and where color came from. I had made it clear that everything that we saw as colored had the colors that were assigned by international agreement after people had become tired enough of the BWG palette to sit down and make it all change.
In the end, the teacher told him he was wrong and he argued about it so I got a call one day that he had been in trouble at school and that the teacher was not thrilled to hear his explanation so I needed to clear things up for him since he was not inclined to believe her at all. I'm not sure that I ever got that completely cleared up because, to me, it was just too funny that I was the most trusted source.
Thanks TED. R.I.P.
That said, I agree with you!
We'll eventually do that for all of history. At least the history we have samples of or can plausibly recreate.
I'd imagine playing one of those might be like living your life right now. Punctuated by lots of mundane, lifelike moments. Like reading an "internet forum" full of other period appropriate "humans".
