I have kept out of this discussion, even trying not to think to much about it. However, wondering why SWMBO was so interested I took a look at last week's episode. Please note that, particularly with reference to a previous post, my interests might not be the same as hers.
There is research, inadequate research or making it up as you go along - how appalling could the scenes in and around the mine be? With so much information and so many images available how could anyone get it so wrong? Pumping aside (but why?), how do the programme makers think men descended and ore was taken from the mine? Oh!, of course, it was by way of the open ended sheds on the surface, which provided a sort of portal into another dimension, transporting those who enter vertically down (was it below 55 fathoms in the last episode?) in seconds and back again, carrying the dead and injured back up just as quickly. Nice clean clothes too.
Some authenticity e.g. vertical descents would have added to dramatic effect. Filming time is limited (hence walking in and out of the "portal"?) but did no-one think of that?
The lack of smoke must have been of course, through very efficient firing of the boiler - or was it because Poldark was down to his last bag of coal and was really making it last?
Enough!
