Well, I was expecting at least one factual error - it's normal with TV programmes - and doesn't detract from the presentation at all. A good number of the historical photos used were of the Godstone silver sand pits, not the firestone quarries. It was my fault, I told the production team to check the BGS GeoScenic photo archive for the 1893 underground photo of the working face with all the tools, and they clearly found all the other non quarry related images as well, put two and two together etc etc.
I'll give them 8 out of 10. One mark off for using irrelevant photos, and one mark off for not making the quarry bit a little longer. They left out all the footage of the exposed and conserved tramway which they took just round the corner from the bit they did show. And the Wealden got a good credit at the end just before the "Credits Squeeze".
The Greenhouse was part of our local heritage, I'll have you know, Alex. But if it hadn't burnt down, I expect the Luftwaffe would have done the job a few years later!
