This is a BBC series from about 10 years ago set in Devon, on Exmoor at the time of the Monmouth Rebellion. I liked this adaptation - one of my reenactment friends was armourer on this so maybe I am biased but I thought it was well done. It shows the West as being quite wild which I think it was at the time and shows a part of the world away from the Court and London. Shame they had to film it in Wales though. Looks nothing like Exmoor.
