How is it more accurate? Even if Mel Gibson was made out to be a demigod and English occupation of Scotland was exaggerated to decades (actually more like a few years), the rough timeline of events were still accurate, Wallace did rebel, did win a great victory, he did lead an incursion into English territories(nowhere near Leeds, mind), before being defeated, captured and executed, and Scotland did win independence after his death.
Compare that to Gladiator, Maximus didn’t exist, there was no question over Commodus’s succession, there was no takeover by the Senate after his death, instead the Roman world descended into chaos with the Crisis of the Third Century. It was a well made film with a clear and engaging narrative but the historicity is bungled badly.
