Apparently this movie gets a lot of hate from some people (not the majority) for being historically innacurate. Honestly though, I thought the whole thing was fiction and only after realised it was based on a true story.
Can't people just enjoy the movie? The movie plays out like a legend, not like a history lesson.
The only time I'd ever assume a movie was depicting real events was if it explicitly said so, and even "Based on a True Story" isn't enough. Unless it's specifically a 100% true depiction, or a documentary, I wouldn't even think of considering it accurate in any meaningful way.
Can't people just enjoy the movie?
Well yes, if they know nothing and care less about Scottish or English history, they probably can.
But if you know anything about the people and the issues involved, it's less easy. If somebody made a wildly inaccurate and propagandist film about your own home town, your own family, or anything else important to you, could you blithely ignore the falsification and enjoy it as a legend?
And, more problematically, it was presented as being based on a true story, and a lot of ill-informed people, even here in Scotland, swallowed it, including its misrepresentations of the material culture, not just the political and social misrepresentations and distortion of characters.
