I'm not sure Saladin was completly free of doing some bad things. Any time you take up arms against another person you aren't exactly being generous to them. I think it was probably pretty common practice for both sides to behave badly. I'm sure the movie made a lot of mistakes but I dont go to movies to be educated I go to be entertained. Watch the history channel if you want to enjoy a history lesson. I thought the movie was more along the lines of Scott's idealistic look at the world with some realism. I still liked the flick and would recommend if you are just going to be entertained and not educated.
