As a Christian I loath attacks on the faith (at least unfounded ones). Usually these attacks, such as The Da Vinci Code tend to be tedious affairs but they still get a number of Christians all whipped up. As a general rule Christians react to potential attacks on the faith with a loud whining sound. Even when the perceived attack is actually not intended to be harmful (see the reactions to Evan Almighty) Christians can still become a gaggle huffy sourpusses.
There is a great article on The Golden Compass over at FamilyLife. They speak with Looking Closer Journal's Jeffrey Overstreet about the books and the film and they provide a reasonable approach for Christians.
