Kingdom of Heaven

I *really* want to see this (isn't Orli a dreamboat?), but I am history buff too. My son wants to see it too. He's into D&D and knights and etc (has been for the last 3 years) but I think he just wants to see a really good action flick. It's rated R for violence and some adult content. I was thinking that before I let him see it, he has to do short report on the Crusades so that he at least has some factual context to put the movie in.

I hate how uninformed and easily influenced our kids are growing up to be. There should be absolutely no excuse for the ignorance that is rampant these days, and yet, there it is.
