So, the thing is, Kingdom of Heaven isn't a particularly historical film. It has some cute period details, but character motivations and themes would have been unthinkable in an actual medieval context. It's very, very obviously an analogy for modern political and religious (but mostly political) conflicts.Hades said:On the subject of Kingdom of heaven since it came up, I'd actually say its much worse than Alexander. Alexander was merely boring but Kingdom of Heaven was just offensive. Far too little history, and far too much preaching. Don't get me wrong, I'm no Christian rights activist but it did make me uncomfortable how every Christian was so cartoonishly evil and just wanted to eat Muslim babies for dinner while the few decent ones that are the main characters are actually time traveling atheists in disguise rather than Christians. Heck, even the priest that offered to ransom himself for the sake of his poorer citizens got demonized as a despicable coward because the plot had ran out of Templars to bully.
The film uses historical events and characters, but it's not really about the real events surrounding the fall of Jerusalem, it's about a conflict between intolerance, zeal and superstition and what we would now call secular humanism. All of the major characters are Christians. There are no atheists in the film. Heck, one of the most obvious mouthpieces for the "secular humanist" view is a Hospitaller knight.
So, the central point of the film really is about what Jerusalem represents. Jerusalem is a literal place, but in Christian eschatology it's also the capital of the messianic kingdom, and as such it's used in a lot of societies to describe a kind of perfect or ideal country or society (there's an English patriotic hymn called Jerusalem which is pretty on the nose with this theme). This is the idea of Jerusalem that Balian in the film ultimately comes to, it isn't the physical place which people have fought over for centuries, but the ideal of Jerusalem that matters.
I think the only way this movie could offend a person's Christianity is if they genuinely think that the crusades are a good thing, all other religions are evil and the religious and political system should be explicitly biased towards Christians, in which case I think that's kind of the point. The point is that if you're a Christian today, you should be able to draw a line between yourself and the worst excesses of medieval Catholicism.
The film literally exists because the crusades are still being wheeled out, because "deus vult" is a far right meme and serious political commentators talk about dropping nuclear bombs on countries whose people follow the wrong religion. The point of the movie is that you can't own Jerusalem, or rather, you can't own what Jerusalem represents. The real kingdom of heaven can only be shared.
