The battle scenes where pathetic, they always shown Saladin using superior tactics to the western tactics.
I seem to remember Balian outsmarting him in several of his counter-attacks.
In real life Saladin slottered and inslaved all those he could find. He didn't let the crusaders leave peacefully.
The crusaders was protrude in the move as a bunch of mind numb murderous monsters, even the main actors where murderous.
