The film presents Saladin as a sweetheart, which he wasn’t. He was your typical(for the time) General/Conqueror type. Though I often wonder whether the utter shittiness of the Franks in the levant made him look better to modern eyes.

And it avoids the real reasons Saladin wanted Jerusalem. Which were economic and had nothing to do with religion. Islam didn’t give a crap about Jerusalem until Saladin gave it a reason to.
