I love this movie, despite its inaccuracies.

There are some flaws. I concur. What me rage the most about this movie is when he wakes up on the beach and finds a horse, attached to the ship remnants…

Like… WTF!!!!!! Is that SuperHorse or what?

Another point that made me raise my eyebrows was when he said to Baudouin that they should build the walls of Jerusalem like stars. Which something that was invented several centuries later (17-18-19th century IIRC, could be wrong though). Ok, he was engineer as stated in the movie, but that’s seem to me a bit too much.

That being said.

1. While Templars lack a bit of subtlety. Guy de Lusignan, and especially Renault Le Châtillon, were real assholes, with Renault close to being a psycho. So the movie has a point there. Though, I would have loved the movie to give a more nuanced perspective than a very black and white « Hospitallers / Knights of the Holy Sepulchre good; Templars bad ».
2. About Balian. While Balian was of noble descent, raised in Palestinia, the movie wants to make a point about religion and acting with your soul and hearth. And when you do, you raise yourself above the others. Making Balian a smith (ex soldier), emphasised this perspective. And I’m ok with that.
3. I used to also think Bloom didn’t have the epicness to match with epicness of the setup. But after discussions with others I joined their perspective: see point 2. Putting a Aragorn wouldn’t have fit and wouldn’t have given the same impression as in point 2

With this said, you may dislike the movie as much as you can. None can judge your tastes.
