This was your initial statement. My reaction is that you felt there was no need to make the movie, since the Scriptures were all that was necessary. However, your problem, if I understand your last post, is that people are going to see the movie. This makes less sense than your first statement. Your objections are still, it seems to me, an attempt to attack the movie without addressing the real issue for attacking it. If you have a problem with anything extra Biblical, then you must have a problem with hymns, Ben Hur, the Ten Commandments, and many other extra Biblical attempts to illustrate faith and bring the Gospel message to people who may not have heard it.
In your last post you stated that you're getting the impression that Christians want to make seeing the movie almost mandatory. Trying to chase your arguments around is getting a little too much like the dead parrot skit, so, I'll just accept that you're pinin' for the Fjords and leave you alone.
I agree with you that there are many ways to spread the gospel. A movie is one way. This a movie, a work of art, one man's personal vision. Because of that is it not mandatory that William Safire or anyone else likes it. And because of that people of good will can like it, dislike it, like parts of it, dislike parts of it, or ignore it.
