It is a great movie but it has a very Western perspective to offer, the lack of detail on Saladin, one of the greatest and most successful rulers of Jerusalem, if not the only true saviour of the holy land, seems arrogant. It could have done a bit better to show how Saladin successfully integrated the three religions within the walls and led a prosperous era during his time.
His reference in detail could have inspired people to work for peace and betterment of Jerusalem in our time, the importance of which could not be overstated.
