Sherwood is purely fictional. It takes creative liberties to weave an engaging tale, rather than being rooted in reality. So, don't expect it to be a true account of events.
I don't think it's a true story. 'A Haunting in Sherwood' is probably just a creative concoction to thrill and entertain, rather than being based on actual events.
Yes, 'Sherwood' on Britbox is based on a true story. It draws from real - life events that took place in Nottinghamshire. The show weaves together elements of crime, community, and the complex relationships among the people in that area, bringing to life a story that has roots in actual occurrences.
In general, for any 'Sherwood True Story', the setting is likely to be a key element. Whether it's a physical place like a forest or a town, it will influence the actions and events in the story. Another important element could be the conflict. It could be a conflict between people, or between a person and their environment. And of course, the resolution of that conflict is also a crucial part of the story.
